<p>I currently have the code below which produces a resizable list, except the li elements do not match the height of their neighbor. It's similar to the question <a href="https://stackoverflow.com/questions/17011822/force-all-items-in-list-in-each-row-to-have-the-same-height-each-item-has-dynam">posted here</a> with the exception that the number of items per row should be dynamic.
How can I make each li in a row match that row's highest li while preserving the existing functionality?</p>
<p>List example used in images:</p>
<pre><code> <ul>
<li>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas pharetra nunc vitae massa elementum ultricies a non ipsum.</li>
<li>Nunc porttitor pretium ex, in molestie lacus molestie eget.</li>
<li>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. </li>
<li>Fusce faucibus lacus eu tellus interdum aliquet. Donec euismod nisi eu nisi dictum, a tincidunt sapien dictum.</li>
<li>Fusce aliquet tempus ex quis tincidunt. Donec at varius enim. Nullam elementum laoreet lacus.</li>
<li>Aenean id volutpat ipsum. Maecenas vulputate odio nec lectus vulputate, cursus volutpat nulla vehicula.</li>
<li>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas pharetra nunc vitae massa elementum ultricies a non ipsum.</li>

<li>Aenean id volutpat ipsum. Maecenas vulputate odio nec lectus vulputate, cursus volutpat nulla vehicula.</li>
</ul>
</code></pre>
<p>CSS:</p>
<pre><code>ul {
overflow: scroll;
list-style: none;
resize: horizontal;
height: 30vh;
width: 80vw;
padding: 0px;
}
li {
background-color: grey;
vertical-align: top;
display: inline-block;
width: 20vw;
margin: 2px;
}
</code></pre>
<p>It produces the following output: <a href="https://i.stack.imgur.com/V4IAv.png" rel="nofollow noreferrer">resized to show 4 li per row</a>
<a href="https://i.stack.imgur.com/Se1vX.png" rel="nofollow noreferrer">resized to show 3 li per row</a></p>

<pre><code>def main():
plate = input("Plate: ")
if is_valid(plate):
print("Valid")
else:
print("Invalid")
def is_valid(s):
index = []
for i in s:
if i.isdigit():
index += i
break
print(index)
if 6 >= len(s) >= 2 and s[0:1].isalpha() and s.isupper() and index[0] != '0':
return True
main()
</code></pre>
<p>Before I added and index[0] != '0' the code worked perfectly, but for some reason after adding that piece of code, when I go to input "KEVIN" an error(index out of range) pops up. How do I prevent this error from popping while still checking out the requirements for the code in the if statement?</p>

<p>I want to make a program where 2 options will be written on text and I want to make my program whenever the user choose one of those option the other option will be greyed out.</p>

<p>When new users sign up for our software, I get emails like:</p>
<pre><code>Store Leads Account Created (ammar@123.com)
</code></pre>
<p>I'm trying to isolate the domain name.</p>
<p>I found this regex expression which worked:</p>
<pre><code>.*@(\S+)
</code></pre>
<p>but I get left with a trailing <code>)</code>, so I get:</p>
<pre><code>123.com)
</code></pre>
<p>How do I remove the trailing <code>)</code>, at the end?</p>

<p>Using Node.js, I can pass a handle/ref for a http request to a child process using this construct:</p>
<pre><code>const k = cp.fork(childPath);
const server = http.createServer((req,res) => {
k.send('foo', req.socket);
});
</code></pre>
<p>and in the child process, I can do:</p>
<pre><code>process.on('message', (m, socket) => {
// 'foo', socket
socket.write([
'HTTP/1.1 200 OK',
'Content-Type: text/html; charset=UTF-8',
'Content-Encoding: UTF-8',
'Accept-Ranges: bytes',
'Connection: keep-alive',
].join('\n') + '\n\n');
socket.write(`
<h1> Example </h1>
`);
socket.end('foobar');
};
</code></pre>
<p>which is pretty cool, allows child processes to write directly to requests.</p>
<p>I am wondering, how I can do the same for a websocket server:</p>
<pre><code>const ws = require('ws');
const server = new ws.WebSocketServer({port: 5151});
</code></pre>
<p>I assume passing a connection to a child process should work:</p>
<pre><code>server.on('connection', c => {
k.send('foo', c); /// error here
});
</code></pre>
<p>but I get an <strong>error</strong>, saying:</p>
<p> <code>This handle type cannot be sent</code></p>
<p>not sure if websocket connections have sockets as do http connections?</p>

<p>I'm trying to use docker-compose to run a project with two Docker containers, MySQL and NodeJS. I'm having trouble connect to the SQL container from the backend container. My backend container uses Prisma as it's ORM and shows me the following error when <code>npx prisma migrate dev</code> is ran (during docker-compose up).</p>
<pre><code>Error: P1001: Can't reach database server at `mysql`:`3306`
Please make sure your database server is running at `mysql`:`3306`.
</code></pre>
<p>After some research, I thought the issue was my database url. The host name should match the db container name (mysql in this case), so I updated that but still no luck.</p>
<pre><code>DATABASE_URL=mysql://root:root@mysql:3306/myshowlist # .env file
</code></pre>
<p>I also tried the container service name (db) but that wasn't it either.</p>
<pre><code>DATABASE_URL=mysql://root:root@db:3306/myshowlist # .env file
</code></pre>
<p>What I'm finding puzzling is that my Prisma has no issue connecting to the MySQL container when it's not run inside the container. When I start the MySQL container solo and run the Prisma migrate command, it works and I can use the backend service like normal and save/read from the database. I do have to use localhost as the hostname though which makes sense.</p>
<p>I'm not sure what could be the issue, I would really appreciate a nudge in the right direction!</p>
<p>docker-compose.yml:</p>
<pre class="lang-yaml prettyprint-override"><code>version: "3.8"
services:
api:
build:
context: ./api-old
ports:
- "5001:3200"
container_name: api

container_name: mysql
ports:

</code></pre>
<p>./api-old/Dockerfile:</p>
<pre><code>FROM node:latest

<p>So i need to create a post request that gets login data(name, email, password) from the user, runs validations, encrypts password, then stores data. The problem is that the encryption function takes time to run, and the variable is still not populated by the time i use it. Tried using another promise-await inside but didn't work. How do i wait till encryptedPass is not null?</p>
<pre><code>// Bcrypt import, initialize number of rounds of salting
saltRounds = 10;
router.post('/user/create', bodyPraser.json(), async (req, res) => {
// Some code here that runs validations
// Encrypting password
var passwordToEncrypt = req.body.password;
var encryptedPass;
// MongoDB model to store data
const encryptedData = new Model({
fullname: req.body.fullname,
email: req.body.email,
password: encryptedPass
});
// Salting function
bcrypt.genSalt(saltRounds, function (err, salt) {
// Hashing function
bcrypt.hash(passwordToEncrypt, salt, function (err, hash) {
// Store hash in database here
encryptedPass = hash;
});
});
// Save, and store data. Sedn success.
const dataToSave = await encryptedData.save(); // The password is still null at this point
res.status(200).json(dataToSave);
console.log("Data saved");
}
catch (error) {
res.status(400).json({ message: error.message });
console.log("Data not saved!");
}
})
</code></pre>

<p>im using</p>
<pre><code>df = spark.read.option("header",True) \
.csv("contatcs.csv", sep =',')
</code></pre>
<p>but works to with pyspark.pandas api</p>
<pre><code>import pyspark.pandas as ps
df = ps.read_csv('contacts.csv', sep=',')
df.head()
</code></pre>
<p>but I prefer spark.read because it's a Lazy Evaluation
and the pandas API is not</p>

<p>I'm trying to embed some YouTube videos for a portfolio site. I'm using the embed code given by YouTube itself under one of my videos. But when I use it, I get the "Video Unavailable" error message.</p>
<p>Here's the embed code</p>

<p>This is what you get under the share section, so I assumed it would work. Does anyone know how to solve this?</p>

<p>Before you say that this is a minor problem and was discussed a million times here and on other forums, I want to say that I went through all of them and tried to implement each of their solutions but with no luck. I either missed some very small detail or there is something wrong with my project in general. Hope you might help.</p>
<p><strong>The problem:</strong>
After I've changed the location of "Info.plist" my project shows black screen.</p>
<p>Or I get the following errors:</p>
<p><a href="https://i.stack.imgur.com/RwwnZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RwwnZ.png" alt="enter image description here" /></a></p>
<p><strong>What I've already tried:</strong></p>
<ol>
<li>In "Target membership" checked or unchecked the box with the project name</li>
<li>In "Targets" - "Build settings" - "Info.plist File" changed location to "Personal Quiz/Supporting files/Info.plist" plus tried all the other possible paths.</li>
<li>In "Targets" - "Build Phases" - "Copy Bundle Resources" - deleted and add "Info.plist</li>
<li>In File "Info" - "File Inspector" - "Location" changed to "Absolute path", "Relative to group", "Relative to project" and mirrored chosen path path to "Build settings"</li>
<li>In simulation - "Device" - "Erase all content and settings"</li>
<li>"Command + Shift + K" to clean the project</li>
<li>Tried to read apple developers book</li>
<li>Tried to implement some code</li>
<li>Tried some other actions that I can't even recall</li>
</ol>
<p>As a result I either have a black screen or errors above. What am I doing wrong?</p>

<p>I've been following <a href="https://stackoverflow.com/questions/26921544/drawing-sine-wave-with-increasing-amplitude-and-frequency-over-time">this</a> guide, but I'm having trouble understanding/implementing the formula for AM/FM (Amplitude/Frequency Modulation) in my code. This is how they appear:</p>
<p><code>f(t) = A(t) * sin(2pi * f * t)</code></p>
<p><code>f(t) = sin(2pi * ((f + A(t)) * t))</code></p>
<p>According to the guide/wiki, <code>A(t)</code> is the "message signal" and if I'm increasing the amplitude/frequency linearly, then <code>A(t) = t</code>, where t is just the time, so my code looks like this:</p>
<pre><code>var time: float = 0.0
var frequency: float = 4.0
var amplitude: float = 200.0
var point = Vector2(50.0, 200.0)
func _physics_process(delta):
time += delta
point.y += amplitude * time * cos(frequency * time) * delta
point.x += 100.0 * delta
$Line2D.add_point(point)
</code></pre>
<p>AM:</p>
<p><img src="https://i.stack.imgur.com/PeIpQ.png" alt="AM" /></p>
<p>I'm able to get the amplitude to increase, however, the frequency increases too. Am I doing this wrong? (I use <code>cos()</code> instead of <code>sin()</code> so I don't have to do 2 * pi)</p>
<p>Similarly, I tried doing Frequency Modulation:</p>
<pre><code>func _physics_process(delta):
time += delta
point.y += amplitude * cos((frequency + time) * time) * delta
point.x += 100.0 * delta
$Line2D.add_point(point)
</code></pre>
<p>FM:</p>
<p><img src="https://i.stack.imgur.com/gQVtx.png" alt="FM" /></p>
<p>The frequency increases, but the amplitude decreases.</p>
<p>I've seen other posts that describe the frequency increase as a "chirp", which has the same function as the Frequency Modulation. For reference, this was programmed with GDScript in Godot, which has the (0,0) in the top left, so +X is right and +Y is down.</p>

<p>So basically, the program is a "sales tracker" and we must enter an id, but the id must be only 8 characters long and if it isn't 8 characters long then the program will tell the user so. I've got most of the program done but I cannot seem to get this part of the program done.</p>
<p>The user can also change the id in the database and the id still must be 8 characters long.</p>
<p>This is the full program</p>
<pre><code>

<p>I've tried to do a while loop with id.length != 8, but I keep getting an int cannot be dereferenced error. How can I fix this? Can I fix this? If not, what can I do to make this correct.</p>

<p>Okay, so im new to Unix and I am trying to learn the basics of Unix. I have a file called adafile that im trying to configure and just toy around with. I basically want to print the digits in the second decimal place for the numbers in column 2 (which is 1,3,5,6,4,6,2,4).</p>
<pre><code>File Output:
3.0 .91 7 36 January JAN Wayne Smith
2.8 .83 4 17 February FEB Eric Kittle
5.1 .95 8 15 March MAR Morgan Leach
9.0 .76 7 19 April APR Jane Holder
3.5 .84 4 43 October OCT Victor Carter
5.2 .98 6 13 November NOV Michael John
4.5 .86 2 8 December DEC Harry Kaka
5.7 .96 4 13 September SEP Tim Simple
</code></pre>
<p>How do I go about getting this done without the use of scripts? I tried using the command: nawk '{print $2}' adafile</p>
<pre><code>Output:
.91
.83
.95
.76
.84
.98
.86
.96
</code></pre>
<ul>
<li>but I know it would show all the content in the 2nd column.</li>
</ul>
<p>Should I be using the nawk command or is there a better command for this?</p>
<p>If I could get any help I much appreciate it!</p>

<p>How can I replace values in <code>df1</code> with var values in <code>df2</code> if they match BOTH code1 and code2, and append non-matches to the bottom <strong>keeping the order of df1 AND indexing whether the line was edited</strong>:</p>
<p>Sample data:</p>
<pre><code>#create sample df1
df1 <- data.frame(code1=c("A","B","C","E","E","A"),code2=c("C3","C1","C4","C3","C5","C3"),var1=c(1,2,3,4,5,6),var2=c("vA","vB","vC","vD","vE","vF"),ver=1,stringsAsFactors = F)
#create sample df2
df2 <- data.frame(code1=c("E","B","Z","Z"),code2=c("C3","C1","C3","C5"),var1=c(9,10,1,5),var2=c("vX","vY","vD","vD"),ver=2,stringsAsFactors = F)
</code></pre>
<p>I'd like a function that creates the following result df:</p>
<pre><code>
df_desired <- data.frame(code1=c("A","B","C","E","E","A","Z","Z"),code2=c("C3","C1","C4","C3","C5","C3","C3","C5"),var1=c(1,10,3,9,5,6,1,5),var2=c("vA","vY","vC","vX","vE","vF","vD","vD"),ver=c(1,2,1,2,1,1,2,2),stringsAsFactors = F)

<p>I am trying to create an API (either REST or HTTP API) on AWS that points to some lambda function that can then access the Cloudfront HTTP headers described here:</p>
<p><a href="https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/using-cloudfront-headers.html" rel="nofollow noreferrer">Adding the CloudFront HTTP headers</a></p>
<p>I have been struggling to get these headers added all day. I have tried the following:</p>
<ol>
<li>Cloudfront distribution that points to Http API with a lambda function as a route. The cloudfront distribution has an origin request policy as follows:</li>
</ol>
<p><a href="https://i.stack.imgur.com/Zqkuw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Zqkuw.png" alt="enter image description here" /></a></p>
<p>When I test this, I have no cloudfront headers appearing in the request (when I print the headers in the lambda function).</p>
<ol start="2">
<li>When I try to do the same setup with a REST API, I am able to see the "CloudFront-Viewer-Country" and "CloudFront-Viewer-ASN" but don't see any other cloudfront headers, even with the above origin request policy.</li>
</ol>

<p>Actually I had a doubt reg. <code>UUID().uuidString</code> is <strong>unique for globally like Android, iOS Swift, java and etc</strong>.</p>
<p>UUID is like <code>9297EEEF-FE6D-4758-88BF-4051961B8619</code></p>
<p>am generating unique id for each record in internal Database and for api callings. Same thing other teams(android and web) doing. Is that any possible for duplication?</p>

<p>When I convert the above expression to string, it throws error</p>
<pre><code>html_str = str(html)

<p>I can see the " are already escaped here. do I need to replace /" with //" and then convert to string?</p>

<p>I have a file with two columns separated by tabs as follows:</p>
<pre><code>OG0000000 PF03169,PF03169,PF03169,MAC1_004431-T1,
OG0000002 PF07690,PF00083,PF00083,PF07690,PF00083,
OG0000003 MAC1_000127-T1,
OG0000004 PF13246,PF00689,PF00690,
OG0000005 PF00012,PF01061,PF12697,PF00012,
</code></pre>
<p>I just want to remove duplicate strings within the second column, while not changing anything in the first column, so that my final output looks like this:</p>
<pre><code>OG0000000 PF03169,MAC1_004431-T1,
OG0000002 PF07690,PF00083,
OG0000003 MAC1_000127-T1,
OG0000004 PF13246,PF00689,PF00690,
OG0000005 PF00012,PF01061,PF12697,
</code></pre>
<p>I tried to start this by using awk.</p>
<pre><code>awk 'BEGIN{RS=ORS=","} !seen[$0]++' file.txt
</code></pre>
<p>But my output looks like this, where there are still some duplicates if the duplicated string occurs first.</p>
<pre><code>OG0000000 PF03169,PF03169,MAC1_004431-T1,
OG0000002 PF07690,PF00083,PF07690,
OG0000003 MAC1_000127-T1,
OG0000004 PF13246,PF00689,PF00690,
OG0000005 PF00012,PF01061,PF12697,PF00012,
</code></pre>
<p>I realize that the problem is because the first line that awk grabs is everything until the first comma, but I'm still rough with awk commands and couldn't figure out how to fix this without messing up the first column. Thanks in advance!</p>

<p>I need to clean up a dataframe whose columns come from different sources and have different types. This means that I can have, for example, string columns that contain "nan", "none", "NULL", (as a string instead of a None value).</p>
<p>My goal is to find all empty values and replace them with None. This works fine:</p>
<pre><code>for column in df.columns:
for idx, row in df.iterrows():
if (str(row[column]).lower() == "none") or if (str(row[column]).lower() == "nan") or (str(row[column]).lower() == "null"):
df.at[row.name, column] = None
</code></pre>
<p>But it is obviously not the best or fastest way to do it. How can I take advantage of Pandas operations or list comprehensions to do this substitution? Thanks!</p>

<p>I have classes <code>Employee</code> and <code>Address</code> as follows:</p>
<pre><code>public static class Employee {
private List<Address> address;
// getters, etc.
}
public static class Address {
private String city;
// getters, etc.
}
</code></pre>
<p>I am learning streams, I am trying to iterate over the objects from list of list and create a set of unique values. I was able to get it working by using nested for loop. How can I convert below code to streams?</p>
<pre><code>public static Set<String> getCityUniquName(List<Employee> emp){
Set<String> cityUniquName = new HashSet<>();
for(Employee e: emp){
List<Address> addList = e.getAddress();
for(Address add: addList){
cityUniquName.add(add.getCity());
}
}
return cityUniquName;
}
</code></pre>

<p>I am building an app for iOS and Mac Catalyst and have been able to code most of the
experience that I want except for functions that use swipe to delete in iOS.</p>
<p>The view includes multiple sections, each with a List and ForEach closure. I want to
be able to add the EditButton() function to the header of each section and have it
apply only to that section's List.</p>
<p>I can
add an EditButton() function to gain this functionality, however,
so far I have only been able to make that work for the entire screen, not for the
individual sections.</p>
<p>I have tried refactoring the code for each section into functions and into structs
(as shown below). In all cases the EditButton() activates the delete icons for ALL
list rows, not just the section with the button.</p>
<p><a href="https://i.stack.imgur.com/ALP1C.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ALP1C.png" alt="enter image description here" /></a></p>
<p>I have also tried placing the EditButton() inside the section in the VStack. No difference.</p>
<p>Here's a simple example with the latest code attempt:</p>
<pre><code>struct ContentView: View {
@State private var selectedItem: String?
@State private var items = ["One", "Two", "Three", "Four", "Five"]
@State private var fruits = ["Apple", "Orange", "Pear", "Lemon", "Grape"]
var body: some View {
NavigationSplitView {
ItemSection(selectedItem: $selectedItem, items: $items)
FruitSection(selectedItem: $selectedItem, fruits: $fruits)
} detail: {
if let selectedItem {
ItemDetailView(selectedItem: selectedItem)
} else {
EmptyView()
}
}//nav
}//body
}//struct
struct ItemSection: View {
@Binding var selectedItem: String?
@Binding var items: [String]
var body: some View {
Section {
VStack {
List(selection: $selectedItem) {
ForEach(items, id: \.self) { item in
NavigationLink(value: item) {
Text(item)
}
}
.onDelete { items.remove(atOffsets: $0) }
}
.listStyle(PlainListStyle())
}//v
.padding()
} header: {
HStack {
Text("Section for Items")
Spacer()
//uncomment when you have it working
//#if targetEnvironment(macCatalyst)
EditButton()
//#endif
}//h
.padding(.horizontal, 10)
}//section and header
}//body
}//item section
struct FruitSection: View {
@Binding var selectedItem: String?
@Binding var fruits: [String]
var body: some View {
Section {
VStack {
List(selection: $selectedItem) {
ForEach(fruits, id: \.self) { fruit in
NavigationLink(value: fruit) {
Text(fruit)
}
}
.onDelete { fruits.remove(atOffsets: $0) }
}
.listStyle(PlainListStyle())
}//v
.padding()
} header: {
HStack {
Text("Section for Fruits")
Spacer()
}//h
.padding(.horizontal, 10)
}//section fruit
}//body
}//fruit section
struct ItemDetailView: View {
var selectedItem: String
var body: some View {
VStack {
Text(selectedItem)
Text("This is the DetailView")
}
}
}
</code></pre>
<p>Any guidance would be appreciated. Xcode 14.0.1 iOS 16</p>

<p>I got a project, where a table widget was used instead of DataTable, So I have been able to pull my JSON data to the table row, but I am having issues showing the header for the table, I can use DataTable to achieve, but I am required to use the table widget.</p>
<p>This is what I have done so far</p>
<pre><code>SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: list.isEmpty
? Container(
alignment: Alignment.center,
child: CircularProgressIndicator())
: Table(
columnWidths: const <int, TableColumnWidth>{
0: FixedColumnWidth(50),
1: FixedColumnWidth(300),
2: FixedColumnWidth(150),
3: FixedColumnWidth(300),
4: FixedColumnWidth(150),
5: FixedColumnWidth(300),
6: FixedColumnWidth(300),
},
children: list
.map((item) => _buildTableRow(
item, context))
.toList(),
),
)
</code></pre>
<p>This is my build row function</p>
<pre><code>TableRow _buildTableRow(UserModel item, context) {
return TableRow(key: ValueKey(item.id), children:
[
tablecell(item.name),
tablecell(item.email),
tablecell(item.phone),
]
}
</code></pre>
<p>The challenge is to add titles to the table.</p>

<p>Here's a fun CSS challenge:
I want <code>ol</code> list items spaced horizontally across a <strong>100% screen width (i.e. dynamic/flex)</strong>, with a horizontal line of <strong>border-radius 2px</strong> connecting each list item without introducing html in between <code><li></code> items (introducing other html elements would be an accessibility violation as <code><ol></code> must only contain <code><li></code> children).</p>
<pre class="lang-html prettyprint-override"><code><ol class="list">
<li class="listItem">One</li>
<li class="listItem">Two</li>
<li class="listItem">Three</li>
<li class="listItem">Four</li>

<p>In PHP, C# and may be other languages, why aren't languages developed to reduce writing code that isn't really necessary?</p>
<p>Why for example foreach perform a loop on null array or list?</p>
<p>I'm not a professional programmer, but I think this a common sense.</p>
<p>Thank you.</p>

<p>I have dates of this mixed type, I would like to standardize all of these to the format <code>yyyy-mm-dd</code> and for dates with just the month I would like to use the "average" of the month (e.g. the 15th). For example, <code>October 28, 2021</code> should become <code>2021/10/28</code> and <code>November 2009</code> should become <code>2009/11/15</code>.

<p>I can't understand the difference between the condition checked in a <code>for</code> loop and an <code>if</code> condition. Do both behave in a different way?</p>
<p>When I write:</p>
<pre><code>int num = 10;
for(int i = 0; i < 15 && num; i++){
cout << i << " ";
}
</code></pre>
<p>It only checks whether <code>i < 15</code> and it doesn't check for <code>i < num</code> and prints all the way from 0 to 14.</p>
<p>But at the same time, if I write a <code>if</code> condition like:</p>
<pre><code>if(x < 15 && num)
</code></pre>
<p>It checks for both <code>x < 15</code> and <code>x < num</code>.</p>

<p>I have a div inside reactstrap Modal, I want to call my function which grab's this div's attribute (after it has been rendered). I have tried <code>useEffect</code> on <code>modalShow</code>, I have tried useRef on that div, I have tried calling the function inside the div.</p>
<pre><code><div
custom-attribute="VALUE"
ref={modalRef}
>
{handleModalLoad()}
</div>
</code></pre>
<p>But the problem is that my function i.e. <code>handleModalLoad()</code> gets executed before the modal is rendered therefore I am unable to grab the value from this attribute.</p>

data[, paste0("share_", i) := get(NSW_cols[i]) / get(AUS_cols[i])]
}
</code></pre>
<p>This seems silly for only a few columns, but in reality my application has several thousand columns. Moreover, in my actual application, I need to do more than simply divide one column by the other. Therefore, I am trying to find a solution that will work for any function accepting two numeric vectors as inputs.</p>
<p>The data comes to me in a somewhat random form, so the convenient ordering of the columns in this example is also not something I can use.</p>
<p><strong>Q: What is the best way to compute on many pairs of columns using vectors of names?</strong></p>
<p>Suspicion: Maybe there is a <a href="https://stackoverflow.com/questions/72490154/compute-multiple-new-columns-by-name-pattern-in-r?rq=1">clever way</a> to do this by converting the data to long form? I haven't been able to make it work.</p>

<p>Why when I switch page using Get(()=> Page2 of getX package, the app go back to default theme colors?
I have a custom theme with yellow color, but then it goes back to the flutter blue default color.
Am I missing something?</p>
<p><strong>my code</strong></p>
<pre><code>appBar: AppBar(
title: Text('Profile'),
actions: [
IconButton(
icon: Icon(Icons.edit_note_outlined), onPressed: () {
setState(() {
/*isVisible= !isVisible;
isReadOnly = !isReadOnly;*/
});
Get.to(
AddNewProduct(),
duration: Duration(milliseconds: 300),
transition: Transition.fade
);
},
),
],
),
</code></pre>
<p><strong>my main</strong></p>
<pre><code> Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(GetMaterialApp(
home: const MyApp(),)
);
}
</code></pre>
<p><strong>my custom theme</strong></p>
<pre><code>@override

<p>I got 3 external images and a div, I need that when I place the mouse over any of the 3 images that image gets to be the backgroundImage of the div and when I mouse out of the div I need the div to get it's original background.</p>
<p>My CodePen</p>
<p><a href="https://i.stack.imgur.com/WUx1F.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WUx1F.png" alt="enter image description here" /></a></p>
<p>That's how far I could get but my code only shows the first of the three images and I know it's because of the index 0 but I just don't know how to solve it. Please guys help me out I beg you!</p>

<p>I am trying to put a series of multiplications inside a list, I am using the code below:</p>
<pre><code>listx = []
for i in range (2):
list = [(3*i)]
listx.append(list)
</code></pre>
<p>The problem is that this will put the two results inside two separate lists inside a lists, I just wants the floats to be inside the first list.</p>

<p>So I recently started coding and just learned about 'try' and 'except' for 'ValueError'. I made this calculator but it restarts if you don't input an int on the 'second' input. How do I make it ask for pnly the 'second' variable instead of asking for the first one again?</p>
<pre><code>while True:
try:
first = int(input("First: "))
second = int(input("Second: "))
sum = first + second
print(f"Sum: {sum}")
break
except ValueError:
print("I didn't understand that")
</code></pre>

<p>I am creating an application where I need to have 3 heirarchy for email folders and notes like this: <a href="https://i.stack.imgur.com/vNFNE.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vNFNE.png" alt="Diagram" /></a>
Now I'm not able to get the list of documents under the <strong>folder</strong> collection.</p>
<p>I have tried this till now:</p>
<pre><code>var collection = FirebaseFirestore.instance
.collection('user')
.doc(widget.email)
.collection('folder2');
await collection.get().then((snap) {
data = snap.size;
print(data);
});
</code></pre>
<p>But this is just giving me 0 in the console, but showing all the entries for the notes collection so what should I do?</p>

<p>in_val = list(range(30,50)) # no of rows dropped
df.drop(in_val, inplace=True)</p>
<p>The the df is with 980 rows, but the index is not 0-979.
How can I do it?</p>

<pre><code> obj = parser.parse(new FileReader("path of json"));
jsonObject = (JSONObject) obj;
String jsonString = jsonObject.toJSONString();
Map<String, String> body = new ObjectMapper().readValue(jsonString, HashMap.class);
response = RestAssuredExtension.PostOpsWithBody(url, body);
</code></pre>
<p>This code gives class cast exception at
jsonObject = (JSONObject) obj; when I pass a json array.</p>

<p>After joined 2 tables and the results as following. I would like to remove some extra rows.
<a href="https://i.stack.imgur.com/LmPHR.png" rel="nofollow noreferrer">enter image description here</a></p>
<p>For example: Id a13b has status2 = Error and Success, I need to remove the row where ID = a13b and status2 = Success same as ID a15b and a16c from the table.</p>
<p>This is the result I am looking for and would like to know what's the correct query to get this result.

<p>I need to simplify two lists using LINQ keeping their index and removing pairs that might have a null/empty partner. Or if I could combine them into a dictionary of key-value pairs (int and decimal) that will also be great.</p>
<pre><code>list1=["1","2","4","5","6"]
list2=["20.20","","",50.0,""]
</code></pre>
<p>to</p>
<pre><code>list1=["1","5"]
list2=["20.20","50.0"]
</code></pre>
<p>I get the lists from a form collection of paymentcategory and amounts. The categories and amounts are dynamically generated.</p>

<p>I have created a API in WSO2 studio integrator like below:</p>
<p>curl --location --request POST 'http://localhost:8290/internal/send-messages' <br />
--header 'accept: text/plain' <br />
--header 'Content-Type: application/json' <br />
--data-raw '{
"bankName": "heere",
"uniqueIdentifier": "445334564"
}'</p>
<p>To pass the requests (which received from this API) toward the endpoint, I need to add two following parameters into API Header</p>
<p>--header 'MasterName: TOMSON' <br />
--header 'clientName: TOM' \</p>
<p>TOMSON value is unique(static) and would NOT change for any user.
However TOM would be change based on application username given from API Manager (there is OATH2 authentication).</p>
<ol>
<li><p>How can I add a static header (Like MasterName) to a API while sending toward the endpoint</p>
</li>
<li><p>How can I understand the username of application ??</p>
</li>
</ol>

<p>I have a set of files with similar naming pattern. I am trying to get the total row count of all the files combined sans the header in a go. But I am having trouble with the commands.</p>
<p>I have tried:</p>
<p><code>sed '1d' IN-Pass-30* | wc -l</code></p>
<p>and</p>
<p><code>awk 'END {print NR-1}' IN-Pass-30*</code></p>
<p>But each time it only subtracts the header count from just one file. What am I doing wrong here?</p>

This needs to be done in pure css.</p>
<p>I tried to do, nothing happened, it does not work correctly:</p>
<pre><code>display: inline-block;
width: 165px;
text-align: center;
color: #fff;
background: linear-gradient(180deg, #4b3529 21%, #4c2e1a 100%);
border-radius: 5px;
border: 1px solid #ffffff;
font-family: Arial;
font-weight: normal;
border-left: 2px solid #e5ccaf;
border-image: linear-gradient(to bottom, #ffd400,rgba(0, 0, 0, 0)) 0 100%;
border-top: 1px solid #ffd400;
</code></pre>
<p><img src="https://i.stack.imgur.com/nhY8Q.png" alt="enter image description here](https://i.stack.imgur.com/nhY8Q.png)" /> <br />
How can I do that?!</p>

<p><a href="https://i.stack.imgur.com/pLi7T.png" rel="nofollow noreferrer">Problem Statement</a></p>
<p>Edit: I have transcribed the image as suggested although I think some terms are better shown in the picture if anything is unclear here;</p>
<p>This function takes in a positive integer n and returns the sum of the following series Sn, as long as the absolute value of each term is larger than stop.</p>
<blockquote>
<p>Sn= 1 − 1/2 + 1/3 − 1/4 + ... + (−1)<sup>n+1</sup>/n + ...</p>
</blockquote>
<p>You can assume that stop is a float value and 0 < stop < 1.</p>
<p>You need not round the output.</p>
<p>For example, if stop = 0.249, then Sn is evaluated with only four terms.</p>
<blockquote>
<p>Sn = 1 − 1/2 + 1/3 − 1/4</p>
</blockquote>
<p>For example, if stop = 0.199, then Sn is evaluated with only five terms.</p>
<blockquote>
<p>Sn = 1 − 1/2 + 1/3 − 1/4 + 1/5</p>
</blockquote>
<p>The built-in function abs() is useful. You should use a while loop.</p>
<p>Test cases:</p>
<pre><code>print( alternating_while(0.249) )
print( alternating_while(0.199) )
</code></pre>
<p>gives:</p>
<pre class="lang-none prettyprint-override"><code>0.5833333333333333
0.7833333333333332
</code></pre>
<p>Now for this question, I want to get the sum of this series based on the conditions stipulated in the question.</p>
<p>My problem is I don't understand how to type the formula given in the question because I'm not familiar with how the while-loop works. Can someone instruct me on how to?</p>
<pre><code>def alternating_while(stop):
total = 0
n = 1
term = 1
while abs(term) > stop:
total= (-1) ** (n + 1) / n + alternating_while(n - 1)
return total
</code></pre>

<p>So, this is the line of code:</p>

<p>Now, I need to disable a certain button if this request is in loading phase. But, I'm stuck on how to solve this issue.</p>

<p>So far the in my html file I have a canvas and a div tag. The div tag contains four paragraph tags which I'm trying to set at the top of the screen, in the middle, and inline. The problem arises when I set them inline and try to add some padding to it. The the third paragraph suddenly just drops to under the first paragraph. Heres the css and html right now.</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>body {
width: 100%;
height: 100%;
border: 1px solid azure;
}
canvas {
display: block;
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
width: 100%;
height: 100%;
user-select: none;
background-color:rgb(33, 96, 33);
border: 1px solid azure;
}
div {
position: absolute;
font-size: 130%;
color:azure;
}
p {
transition: opacity 0.3s ease-in-out;
color:azure;
border: 1px solid azure;
display: inline;
padding-right: 10%;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><canvas id="canvas1"></canvas>

</div></code></pre>
</div>
</div>
</p>
<p>I tried getting rid of all the margin and padding so I did</p>
<p>margin: 0;
padding: 0;</p>

<p>** I AM NEW TO PYTHON **</p>
<p>I would like to know how to write a function that returns True if the first string, regardless of position, can be found within the second string by using two strings taken from user input. Also by writing the code, it should not be case sensitive; by using islower() or isupper().</p>
<p>Example Outputs:</p>
<blockquote>
<p>1st String: lol</p>
<p>2nd String: Hilol</p>
<p>True</p>
</blockquote>
<blockquote>
<p>1st String: IDK</p>
<p>2nd String: whatidk</p>
<p>True</p>
</blockquote>
<p>My code:</p>
<pre><code>a1 = str(input("first string: "))
a2 = str(input("second string: "))
if a2 in a1:
print(True)
else:
print(False)
</code></pre>
<p>It outputs:</p>
<blockquote>
<p>1st String: lol</p>
<p>2nd String: lol</p>
<p>True</p>
</blockquote>
<blockquote>
<p>1st String: lol</p>
<p>2nd String: HIlol</p>
<p>False #This should be true, IDK why it is false.</p>
</blockquote>
<p>I only came this far with my code (I KNOW IT LACKS A LOT FROM THE INSTRUCTION). Hoping someone could teach me what to do. Thank you!</p>
<p>EDIT: I FOUND OUT THAT, MY CODE SHOULD HAVE BEEN:</p>
<pre><code>a1 = str(input("Enter the first string: "))
a2 = str(input("Enter the second string: "))
if a1 in a2:
print(True)
else:
print(False)
</code></pre>
<p>But now, how do I make it not case sensitive?</p>

<p>Recently, I try to migrate to Jetpack compose.</p>
<p>So, I want to show 'card' where has 'indicator' while loading
but I can't change 'indicator' size in 'SubcomposeAsyncImage'</p>
<pre><code>@Composable
private fun SponsorDialogContent(
imgUrl: String,
) {
Card(
modifier = Modifier
.width(300.dp)
.wrapContentHeight(),
elevation = CardDefaults.cardElevation(0.dp),
shape = RoundedCornerShape(10.dp)
) {
Box() {
SubcomposeAsyncImage(
modifier = Modifier
.fillMaxWidth()
.wrapContentHeight()
.heightIn(min = 200.dp),
model = imgUrl,
contentDescription = null,
loading = {
CircularProgressIndicator(modifier = Modifier.size(30.dp).align(Alignment.Center), progress = 1f)
},
alignment = Alignment.Center,
contentScale = ContentScale.FillWidth
)
CircularProgressIndicator(1f, Modifier.width(30.dp).align(Alignment.Center))
}
}
}
</code></pre>
<p>So. I have try the code below</p>
<pre><code>@Composable
private fun SponsorDialogContent(
imgUrl: String,
) {
Card(
modifier = Modifier
.width(300.dp)
.wrapContentHeight(),
elevation = CardDefaults.cardElevation(0.dp),
shape = RoundedCornerShape(10.dp)
) {
Box() {
SubcomposeAsyncImage(
modifier = Modifier
.fillMaxWidth()
.wrapContentHeight()
.heightIn(min = 200.dp),
model = imgUrl,
contentDescription = null,
loading = {
Box(contentAlignment = Alignment.Center) {
CircularProgressIndicator()
}
},
alignment = Alignment.Center,
contentScale = ContentScale.FillWidth
)
}
}
}
</code></pre>
<p>Then, works well, but I don't know why
Does anyone know why?</p>
<p>I tried to find how to work this code but failed</p>

<p>instead of using <code>try and catch</code>, there is any other solution for these <strong>sytnx</strong></p>
<pre><code>const { person, children, total } = response.data // what i looking for
</code></pre>
<p>in case the person response is null , so i got an error <strong>cannot read properties null</strong>.
in other case i only know using <strong>elvis operator</strong> <em>data?.data</em>. thats mean <code>response.data?.person</code> but i want the above code works with <strong>null safety</strong>, its possible ? .</p>
<p><strong>response</strong></p>
<pre><code>data: {
person: null, // these array of object
children: {
data: 'x',
...
...
},
total: 1

<p>I don't think my question is a duplicate because I am not asking how to convert Lists in to CSVs. But: <br/>
I am trying to convert a list into a comma-delimited csv file.<br/>
However, some fields contain commas and semicolons.<br/>
A column will be split into at least two columns when there is a comma.<br/>
<br/>
<strong>My codes:</strong></p>
<pre><code>public void SaveToCsv<T>(List<T> listToBeConverted)
{
var lines = new List<string>();
IEnumerable<PropertyDescriptor> props = TypeDescriptor.GetProperties(typeof(T)).OfType<PropertyDescriptor>();
//Get headers
var header = string.Join(",", props.ToList().Select(x => x.Name));
//Add all headers
lines.Add(header);
//LinQ to get all row data and add commas to serperate them
var valueLines = listToBeConverted.Select(row => string.Join(",", header.Split(',').Select(a => row.GetType().GetProperty(a).GetValue(row, null))));
//add row data to List
lines.AddRange(valueLines);
...
}
</code></pre>
<p>How do I modify the LinQ statment to add double quotes to the start and the end of the string when it is <code>System.String</code>?</p>

<p>I have a Dictionary here:</p>
<pre><code>test_dict = {'gfg': ['One', 'six', 'three'],
'is': ['seven', 'eight', 'nine'],
'best': ['ten', 'six']}
</code></pre>
<p>I tried:</p>
<pre><code>for i in range(len(test_dict)):
values = list(test_dict.values())
keys = list(test_dict)
value_sorted_list = values[i]
value_sorted_list = keys[i]
keys_sorted_list = random.shuffle(value_sorted_list)
test_dict.update({f"{keys_sorted_list}":value_sorted_list})
</code></pre>
<p>I want to sort the keys alphabetically while the value list by length
Something like this:</p>
<pre><code>test_dict = {'best': ['six', 'ten'],
'gfg': ['One', 'six', 'three'],
'is': ['nine', 'eight', 'seven]}
</code></pre>
<p>I also want another function similar to the one i mentioned above but if the elements are similar length, to sort them randomly.</p>
<p>As well as another function to sort value list randomly.</p>

<p>One <code>DropdownItem</code> contains a search <code>Input</code> so when the user clicks on it, I need the drop down menu to remain open so that he types what he needs to search:</p>
<pre><code>import React, { Component } from "react";
import { connect } from "react-redux";
import {
Dropdown,
DropdownToggle,
DropdownMenu,
DropdownItem,
} from "reactstrap";
import SearchBar from "./SearchBar";
export class AddToCollectionButton extends Component {
constructor(props) {
super(props);
this.state = {
dropdownOpen: false,
};
this.toggle = this.toggle.bind(this);
}
toggle() {
this.setState({ dropdownOpen: !this.state.dropdownOpen });
}
render() {
return (
<Dropdown
isOpen={this.state.dropdownOpen}
toggle={this.toggle}
// color="default"
className="div-inline float-right ml-1"
direction="left"
>
<DropdownToggle
tag="span"
onClick={this.toggle}
data-toggle="dropdown"
aria-expanded={this.state.dropdownOpen}
color="danger"
>
<span className="badge badge-danger cursor-pointer-no-color">
<i class="fa fa-plus" aria-hidden="true" />{" "}
</span>
</DropdownToggle>
<DropdownMenu className="dropdown-danger scrollable-drop-down-menu">
<DropdownItem
onClick={(e) => {
// e.preventDefault();
// e.stopPropagation();
// this.setState({
// dropdownOpen: true,
// });
}}
>
<SearchBar />
</DropdownItem>
</DropdownMenu>
</Dropdown>
);
}
}
const mapStateToProps = (state) => ({});
const mapDispatchToProps = {};
export default connect(
mapStateToProps,
mapDispatchToProps
)(AddToCollectionButton);
</code></pre>
<p>I tried different things as you can see inside the <code>onClick</code> and other things mentioned on similar questions on SO but nothing worked.</p>

<p>I am trying to load favicon from assets in nuxt 3 but it does not work except if I hardcode _nuxt in front of it. My config looks like this and this works:</p>
<pre class="lang-js prettyprint-override"><code> export default defineNuxtConfig({
app: {
head: {
link: [{ rel: 'icon', type: 'image/png', href: '_nuxt/assets/favicon.png' }]
}
},
</code></pre>
<p>But according to documentation it should be something like this:</p>
<pre class="lang-js prettyprint-override"><code> ~assets/favicon.png
</code></pre>
<p>or</p>
<pre class="lang-js prettyprint-override"><code> ~/assets/favicon.png
</code></pre>
<p>but both don't work.<br />
Any way to do it as documented or is this a bug?</p>
<p>AddOn Info: If using the links in a vue component it works and the favicon loads correctly if I show it on the page.</p>

<p>In my code every time a page loads, it grabs the departments that page is related to from the WordPress taxonomy and builds an array that is sent to a datalayer variable in tag manager. for example:</p>
<p>in PHP</p>
<pre class="lang-php prettyprint-override"><code>$department = ["accounting", "sales", "support"];
</code></pre>
<p>and in JS</p>
<pre class="lang-js prettyprint-override"><code>window.dataLayer = window.dataLayer || [];
dataLayer.push({
'department': '<?php echo $department; ?>'
});
</code></pre>
<p>in GTM, I want to create a pageview trigger called sales_pageview which fires a tag every time a page loads where "department" contains "sales" and I am not sure how to parse that array in GTM to look for that array element.</p>
<p>Any suggestions anyone? I added some screenshots for reference:</p>

<p>I am using Ansible to create a distributed cluster, which requires multiple data disks and mount directories.</p>
<p>I am trying to complete requirement by defining the below variables, in my inventory:</p>
<pre class="lang-ini prettyprint-override"><code>[all:vars]
minio_plate = [ { "disk_dirve": ["/dev/sdb","/dev/sdc","/dev/sdd"], "minio_data_dir": ["/minio/disk1","/minio/disk2","/minio/disk3"] } ]
</code></pre>
<p>This is my playbook:</p>
<pre class="lang-yaml prettyprint-override"><code>- hosts: 10.102.26.31
tasks:
- name: Mount DVD read-only
mount:
path: "{{item.minio_data_dir}}"
src: "{{item.disk_dirve}}"
opts: defaults,noatime
dump: "0"
passno: "2"
fstype: xfs
state: present
with_items:
- "{{minio_plate}}"
</code></pre>
<p>Results of the task in <code>/etc/fstab</code> (reduced to the relevant part of the file):</p>
<pre class="lang-none prettyprint-override"><code>['/dev/sdb',\040'/dev/sdc',\040'/dev/sdd'] ['/minio/disk1',\040'/minio/disk2',\040'/minio/disk3'] xfs defaults,noatime 0 2
</code></pre>
<p>The result I do expect would be that <code>/etc/fstab</code> contains:</p>
<pre class="lang-none prettyprint-override"><code>/dev/sdb /minio/disk1 xfs defaults,noatime 0 2
/dev/sdc /minio/disk2 xfs defaults,noatime 0 2
/dev/sdd /minio/disk3 xfs defaults,noatime 0 2
</code></pre>

<p>I am trying to use the combineLatest with reactive form's valueChanges method in NgOnInIt hook. My use case is below.</p>
<p>I want to show the name which received from Observable1$ in the form using patchValue() from Reactive forms. This name field is editable which means
when user wants to edit the name which is already shown in the form, I want to check if the name is not the same and if it is not then I want to enable the button to
call PUT method. Hence, I want to use combineLatest from RxJS to handle this behavior but I am not able to do that so. Below errors I am getting.</p>
<p>Actual Behaviours:</p>
<ol>
<li>I get error saying that Maximum call stack size exceeded because of updateValueAndValidity() as it goes into infinite loop.</li>
<li>I did add {emitEvent: false} in patchValue() but when I tried to edit the field, due to this {emitEvent: false}, nothing is emitting anymore.</li>
</ol>
<p>Expected behaviour:</p>
<p>Formfield should show the data which I received from observable1$ (ex: testName).
When I want to edit this field (ex: testNameE), valueChanges method should emit {description: testNameE} value.</p>
<p>How I am trying to achieve this.</p>
<p>form-component.ts</p>
<pre><code> ngOnInit() {
combineLatest([
this.observable1$.pipe(startWith(null)), - provides name
this.form.valueChanges.pipe(startWith(null)), - wants to get the input from the user when he tried to change the name
]).pipe(
tap(([name, formData]) => {
if (name) {
this.patchValue(name);
}
if (formData) {
// check the name is different than received from observable1$,
// if yes, enable button
}
}),
).subscribe();
}
patchValue(name: string) {
this.form.patchValue({
name: name,
});
this.form.updateValueAndValidity();
}
</code></pre>
<p>Can someone please tell me what I am doing wrong here. Any kind of help is appreciated.</p>
<p>Below is the link for stackblitz.

<p>Say I have 2 list columns like below:</p>
<pre><code>group1 = [['John', 'Mark'], ['Ben', 'Johnny'], ['Sarah', 'Daniel']]
group2 = [['Aya', 'Boa'], ['Mab', 'Johnny'], ['Sarah', 'Peter']]
df = pd.DataFrame({'group1':group1, 'group2':group2})
</code></pre>
<p>I want to compare the two list columns and remove the list elements from <code>group1</code> if they are present in <code>group2</code>. So expected results for above:</p>
<pre><code> group1 group2
['John', 'Mark'] ['Aya', 'Boa']
['Ben'] ['Mab', 'Johnny']
['Daniel'] ['Sarah', 'Peter']
</code></pre>
<p>How can I do this? I have tried this:</p>
<pre><code>df['group1'] = [[name for name in df['group1'] if name not in df['group2']]]
</code></pre>
<p>But got errror:</p>
<pre><code>TypeError: unhashable type: 'list'
</code></pre>
<p>Please help.</p>

<p>So in the if-statement, I want to print a message if the player doesn't input the correct things. The problem is that when I start up the code and type something random, it jumps to the first if where it checks yes and moves on. It even replied to the next function for me. Is there a way to fix this?</p>
<pre><code>import time
yes_no = ['yes', 'y', 'no', 'n']
directions = ['north', 'n', 'south', 's', 'east', 'e', 'west', 'w']
else_msg = "Invalid command"
def start():
print("-------------------------------")
print("Welcome to Haunted Funhouse")
print("Do you want to proceed? (y/n)")
cmd = input(">")
if cmd in yes_no:
if cmd == "yes" or "y":
time.sleep(1)
print("\n------------------")
print("Get ready")
print("--------------------\n")
starting_room()
elif cmd == "no" or "n":
time.sleep(1)
print("Okay, shutting down")
quit()
else:
print(else_msg)
def starting_room():
print("-----------Start-----------")
print("You stand in a octagon room")
print(
"There are windows to the northwest, northeast, southeast, southwest")
print("There are doors to the:\n- North\n- South\n- East\n- West")
print("---------------------------------------------------------")
print("Where do you want to go? (n/s/e/w)")
cmd = input(">")
if cmd in directions:
if cmd == "north" or "n":
time.sleep(1)
print("You enter through the north door")
elif cmd == "south" or "s":
time.sleep(1)
print("You go through the south door")
elif cmd == "west" or "w":
time.sleep(1)
print("You enter through the west door")
elif cmd == "east" or "e":
time.sleep(1)
print("You enter through the east door")
else:
print(else_msg)
start()
</code></pre>
<p>I've tried changing '''if cmd not in yes_no''' to '''if cmd in yes_no''', but it didn't work. I ran it through Thonny and the code checker said it was fine</p>

<p>Protobuf definations are like that:</p>
<pre class="lang-protobuf prettyprint-override"><code>syntax = "proto3"
message HugeMessage {
// omitted
}
message Request {
string name = 1;
HugeMessage payload = 2;
}
</code></pre>
<p>In a situation I received a <code>HugeMessage</code> from somebody, and I want to pack it with additional fields, and then transmit the message to someone else. So that I have to <em>Unmarshal</em> the <code>HugeMessage</code> binary into Go structure, pack it into <code>Request</code>, and <em>Marshal</em> again. Due to the hgue size for <code>HugeMessage</code>, the cost for <em>Unmarshal</em> and <em>Marshal</em> are unaffordable. so could I reuse the <code>HugeMessage</code> binary without change the protobuf definations?</p>
<pre class="lang-golang prettyprint-override"><code>func main() {
// receive it from file or network, not important.
bins, _ := os.ReadFile("hugeMessage.dump")
var message HugeMessage
_ = proto.Unmarshal(bins, &message) // slow
request := Request{
name: "xxxx",
payload: message,
}
requestBinary, _ := proto.Marshal(&request) // slow
// send it.
os.WriteFile("request.dump", requestBinary, 0644)
}
</code></pre>

<p>I don't understand how can I autofill a formula that is on a cell to a new column added on the left.
Let's make an example:
<a href="https://i.stack.imgur.com/WcV5c.png" rel="nofollow noreferrer">[Example](https://i.stack.imgur.com/ufCvH.png)</a>
I have on cell "B2" a date that is "B1+180", when I add a new column on the left of "B2", the new "B2" does not contain the formula. How can it autofill the formula when adding new column on the left?</p>
<p>Thanks.</p>
<p>I'm expecting that when I add a new column on the left of "B2", the new B2 will autofill the formula "B1+180".</p>

<p>I have learned that what is the Equatable and how can I use it. But I just wonder that why should I use it?</p>
<p>I have found some reasons. One of them, when we wants to compare 2 or more same object from any class, it will use. they aren't same even if they properties same because of hash code. But equatable compares each other without hash code.</p>
<p>But I really wonder that where I will use in real life scenario?</p>
<p>Many Thanks..</p>

<p>I have this injection VB script that I use for altering C# source code.
This is my current regex match rule I use currently to find code rows with classes in the files:</p>
<pre><code>(public|protected|internal|private|static|abstract)\b\W+(class)\b
</code></pre>
<p>It works and detects class rows, but the problem is it detects all cases in the examples below, while only the first one should be valid.</p>
<pre><code>public class <-- is valid match
//this is a public class comment <-- Should not be valid as match
"This is just a string talking about a public class" <-- Should not be valid match
</code></pre>
<p>To me, what is missing is to have this match rule work is, only allow what is matched by allowed words, and make any other extra a non valid match. Well, a blank space should be the only type that should be allowed.</p>
<p>How to update the current regex to only match the first line of the three examples I just gave?</p>

<p>We have a develop to make some things with bank cards.
One og them is validate the PIN (we have PAN, PIN, Pinlenght and PINBLOCK); and we have a HSM THALES to validate the PIN.</p>
<p>But, how do we connect whith THLALES appliance? I thought that using a library, nugget o similar, but there are no many documentation in internet.</p>
<p>I know the command to send to HSM, expected response, and similar. But.. i can't find documentation about how to connect whit Hardare module.</p>
<p>Any documentation, connection interface, library o similar.</p>

<p>(NOW SOLVED by changing to VS Code instead, works like a charm. :) )</p>
<p>I am quite a beginner in coding, trying to complete a programming assignment focused on Python. I followed along with Tech with Tim's YouTube video about "Python Website Full Tutorial - Flask, Authentication, Databases & More". Link: <a href="https://www.youtube.com/watch?v=dam0GPOAvVI" rel="nofollow noreferrer">https://www.youtube.com/watch?v=dam0GPOAvVI</a></p>
<p>I have followed the code exactly up until 13:36, where he accesses the website url (<a href="http://127.0.0.1:5000" rel="nofollow noreferrer">http://127.0.0.1:5000</a>). I have tried this, yet I got a 127.0.0.1 refused to connect error.</p>
<p><a href="https://i.stack.imgur.com/KMbii.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/KMbii.jpg" alt="enter image description here" /></a></p>
<p>I have tried to follow many different tutorials on how to fix this error, but to no avail.
I tried:</p>
<ul>
<li>flushing the dns</li>
<li>disabling the firewall (real pain)</li>
<li>browser HSTS settings</li>
</ul>
<p>I would have tried asking my teacher, but she already got lost when I tried to explain about front-end and back-end and claimed that I was "too advanced". I can't ask the other groups either as it seems they might not have started coding yet at all, and my own group does not specialize in coding, more on simple interface designing. In canva.</p>
<p>I am now starting to suspect that it might be a problem with the website I am using to code. I am using codecademy's workspaces since we are only allowed to code online because my teacher does not want to download any files on her computer. Should I perhaps change to another one instead?</p>
<p>I have downloaded pip yesterday and made sure I downloaded all of the necessary modules, but it doesn't help the problem.</p>
<p>This is the fourth day that I have been stuck on this on, and now I've really hit a brick wall. I'm stuck, and I'm not sure what to do next. I am no programmer, I don't think that I can even be classified as a decent one just yet. I'm simply a student who is forced to learn by myself because I can't rely on my own class to teach me.</p>

<p>I want to check if an id already exists or not in local-storage, because I want to display specific button if it does. How can I achieve that?</p>
<p><a href="https://i.stack.imgur.com/ecnHb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ecnHb.png" alt="enter image description here" /></a></p>
<p>here is my code</p>
<pre><code>export class FoodPageComponent implements OnInit {
buttonShow = false;
food!: Food;
constructor(
activatedRoute: ActivatedRoute,
foodService: FoodService,
private cartService: CartService,
private router: Router
) {
activatedRoute.params.subscribe((params) => {
if(params.id)
this.food = foodService.getFoodById(params.id);
})
}
ngOnInit(): void {
}
addToCart() {
this.cartService.addToCart(this.food);
this.router.navigateByUrl('/cart-page');
}
}
</code></pre>
