74,250,201 | <p>I have a table called <code>Sets</code> for LEGO:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>set_number (Primary Key)</th>
<th>set_name</th>
<th>other_fields</th>
</tr>
</thead>
<tbody>
<tr>
<td>123</td>
<td>Firetruck</td>
<td>abc</td>
</tr>
<tr>
<td>234</td>
<td>Star Wars</td>
<td>abc</td>
</tr>
</tbody>
</table>
</div>
<p>I have another table called <code>Parts</code> for LEGO:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>part_number (Primary Key)</th>
<th>name</th>
<th>set_number (references set_number from Sets)</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Truck Roof</td>
<td>123</td>
</tr>
<tr>
<td>2</td>
<td>Truck Body</td>
<td>123</td>
</tr>
<tr>
<td>3</td>
<td>Neimoidian Viceroy Robe</td>
<td>234</td>
</tr>
</tbody>
</table>
</div>
<p>I want to create another column in the <code>Sets</code> table to indicate the number of unique parts the particular set has.</p>
<p>I was able to output the number of unique parts with the following:</p>
<pre><code>SELECT s.set_number, COUNT(*) AS num_diff_parts
FROM Sets s, Parts p
WHERE p.set_number = s.set_number
GROUP BY s.set_number
</code></pre>
<p>This outputs the following table (let's call it <code>results</code>):</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>set_number</th>
<th>num_diff_parts</th>
</tr>
</thead>
<tbody>
<tr>
<td>123</td>
<td>2</td>
</tr>
<tr>
<td>234</td>
<td>1</td>
</tr>
</tbody>
</table>
</div>
<p>However, I wonder if I can put the column (<code>num_diff_parts</code>) into the Sets table as a new column, instead of having to run this query every time when I need this information, or create another table just to contain the content of the <code>results</code> table.</p>
<p>Ideally, the <code>Sets</code> table should look like this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>set_number (Primary Key)</th>
<th>set_name</th>
<th>other_fields</th>
<th>num_diff_parts</th>
</tr>
</thead>
<tbody>
<tr>
<td>123</td>
<td>Firetruck</td>
<td>abc</td>
<td>2</td>
</tr>
<tr>
<td>234</td>
<td>Star Wars</td>
<td>abc</td>
<td>1</td>
</tr>
</tbody>
</table>
</div>
<p>I've also tried to do <code>GROUP BY</code> on multiple fields, but I don't think that's safe to do as those fields can have repeats and will throw off the results.</p>

74,250,301 | <p>I have a file aa.txt:</p>
<pre><code>Nothing is worth more than the truth.
I like to say hello to him.
Give me peach or give me liberty.
Please say hello to strangers.
I'ts ok to say Hello to strangers.
</code></pre>
<p>I tried with code:</p>
<pre class="lang-perl prettyprint-override"><code>use strict;
use warnings;
my $input_aa='aa.txt';
while (1) {
print "Enter the word you are looking for (or 'quit' to exit): ";
my $answer = <STDIN>;
chomp $answer;
last if $answer =~/quit/i; #
print "Looking for '$answer'\n";
my $found = 0;
open my $f, "<", $input_aa or die "ERROR: Cannot open '$input_aa': $!";
while (<$f>) {
m/$answer/ or next;
$found=1;
last;
}
close $f;
if ($found) {
print "Found $answer!\n";
while ( my $line = <$input_aa> ) {
print $line;
}
} else {
print "Sorry - $answer was not found\n";
}
}
</code></pre>
<p>I want when I enter a keyword from the keyboard to compare in the file and output the line with that word. For example, when I enter the word <code>Nothing</code>, it should output the line <code>Nothing is worth more than the truth.</code>.</p>
<p>I tried with the code but it doesn't output the line when I enter the keyword from the keychain. Where's the problem?</p>

74,250,329 | <p>I have a DataFrame that I am adding data to, but I do not gather the data for each row at the same time. Some of the columns are assembled in pieces.</p>
<p>The first time I have some data for a column, I can simply assign it:</p>
<pre class="lang-py prettyprint-override"><code>import pandas as pd
df = pd.DataFrame()
df["name"] = pd.Series(["A", "B", "C", "D", "E", "F", "G", "H", "I"])
df["data"] = pd.Series([1, 2, 3])
new_data = pd.Series([4, 5, 6])
</code></pre>
<p>How can I append <code>new_data</code> to the <code>"data"</code> column?</p>
<p>Expected output:</p>
<pre class="lang-py prettyprint-override"><code> name data
0 A 1.0
1 B 2.0
2 C 3.0
3 D 4.0
4 E 5.0
5 F 6.0
6 G NaN
7 H NaN
8 I NaN
</code></pre>
<p>Things I've tried:</p>
<pre class="lang-py prettyprint-override"><code>df["data"] += new_data
# Adds instead of appending
df["data"] = df["data"].append(new_data)
# ValueError: cannot reindex on an axis with duplicate labels
df["data"] = pd.concat([df["data"], new_data])
# ValueError: cannot reindex on an axis with duplicate labels
column = df["data"]
df.drop(columns="data")
df["data"] = pd.concat([column, new_data])
# ValueError: cannot reindex on an axis with duplicate labels
df["data"] = pd.concat([df["data"], new_data], ignore_index=True)
# This doesn't appear to modify the column (but no errors)
df["data"] = pd.concat([df["data"], new_data], axis=1)
# ValueError: Columns must be same length as key
</code></pre>
<p>How can I accomplish this deceptively simple task? I believe I am not understanding how indexing works in Pandas.</p>

74,250,331 | <p>I'm trying to loop through the elements of a list, print them out, separate them by a comma but leave the trailing comma; all in a single loop. I'm aware of the join() method but I wanted to ask if there was a way to complete that within the loop?</p>
<p>This is the code I'm currently working with:</p>
<pre><code>grades = [['A1', 12], ['A2', 18], ['A3', 20], ['A4', 19]]
for i in range(len(grades)):
print(grades[i][0], end = ', ')
</code></pre>
<p>It keeps returning this:</p>
<pre><code>A1, A2, A3, A4,
</code></pre>
<p>How do I stop that last comma from appearing?</p>

74,250,337 | <p>I know similar questions like this have already been asked on the platform but I checked them and did not find the help I needed.</p>
<p>I have some String such as :</p>
<p>path = "most popular data structure
in OOP lists/5438_133195_9917949_1218833?
povid=racking these benchmarks"</p>
<p>path = "activewear/2356_15890_9397775?
povid=ApparelNavpopular data structure

<p>I have a function :</p>
<pre><code>def extract_id(path):
pattern = re.compile(r"([0-9]+(_[0-9]+)+)", re.IGNORECASE)
return pattern.match(path)
</code></pre>
<p>The expected results are 5438_133195_9917949_1218833 and 2356_15890_9397775. I tested the function online, and it seems to produce the expected result but my it's returning None in my app. What am I doing wrong?
Thanks.</p>

<p>From there I have created a code to dynamically <code>render</code> the icon SVG based on the <code>variable</code>. The variable is based on the menu items title.</p>
<pre><code>{% for link in section.settings.link_list.links %}
{% capture icon %}
{{ link.title | downcase | replace: " ", "" | remove: "&" }}

{% render 'icon', icon: icon %}
<a href="{{ link.url }}" class="" role="button" data-bs-toggle="dropdown">

</a>
{% endfor %}
</code></pre>
<p>I seem to receive the correct output, as the class in the SVG file is loaded with the link title, its just the <code>case</code> code doesn't seem to render the SVG content?</p>

74,250,346 | <p>Given a sequence U1, U2, U3,...
and the rule is Ui = U(i-1) - 2*U(i-2)
given the natural number n find Un</p>
<p>Here's my approach</p>
<pre><code>n = int(input())
u1 = 1
u2 = 1
for i in range(n//2-1):
s = u2 - 2*u1
t = s - 2*u2
u1 = s
u2 = t
if n == 3:
print(-1)
elif n % 2 != 0:
print(s)
else:
print(t)
</code></pre>
<p>example give n = 3 then the output will be -1
this works for small number but as the n get bigger it's not correct
Can anyone help?</p>

<p>Hi, in this code block I get the error as mentioned above because of this line -> <code>result.data[j][i] = matrix.data[i][j].</code></p>
<p>I try to call a static transpose method and pass it a matrix, that is already created. For some reason, it throws an error that the given matrix is <strong>undefined</strong> even though it isn't, or is it?</p>
<pre><code>static transpose(matrix) {
let result = new Matrix(this.cols, this.rows);
for (let i = 0; i < matrix.rows; i++) {

<p>I'm following a neural network playlist by daniel Shiffman, and I got the error on this episode linked below.</p>
<p><a href="https://youtu.be/r2-P1Fi1g60?list=PLRqwX-V7Uu6aCibgK1PTWWu9by6XFdCfh" rel="nofollow noreferrer">https://youtu.be/r2-P1Fi1g60?list=PLRqwX-V7Uu6aCibgK1PTWWu9by6XFdCfh</a></p>
<p>I've been stuck with this for so long, so thank you in advance.</p>
<p>Since I'm new to js, I thought passing values or references might not work the same as in Java. So I tried creating a test matrix inside the method but still, it threw the same problem that it is undefined.</p>
<pre><code>static transpose(matrix) {
let test = new Matrix(2,2);
let result = new Matrix(this.cols, this.rows);
for (let i = 0; i < matrix.rows; i++) {
for (let j = 0; j < matrix.cols; j++) {
result.data[j][i] = test.data[i][j];
}
}
return result;

74,250,502 | <p>I'm asking a user to input a number from the keyboard. For example users input 190, How can I compare 190 that user input to the value of the dictionary with the same value? is it equal or not?</p>
<p>This is my code:</p>
<pre><code>my_dict = {'apple': [900, 190], 'orange': [1300, 90], 'pineapple': [550, 13], 'carrot': [600, 60], 'cucumber': [900, 30], 'egg plant': [1100, 20], 'zucchini': [1300, 10], 'garlic': [300, 70]}
for key, value in my_dict:
usernumber = input('Input your number: ')
if usernumber == value:
print("Equal")
else:
print("Not equal")
</code></pre>
<p>For example, if users input the number 190, how can I check this value is in dictionary or not</p>

74,250,507 | <p>Let's say I have a function called <code>linksToAnotherPage</code> that receives an href. How can I check if the href takes you to another page or if it is a
<code>tel:</code> , <code>mailto:</code>, <code>#anchor-link</code>, etc that does not take you to another page?</p>
<pre><code>function linksToAnotherPage(href) {
....
}
linksToAnotherPage('tel:123-456-7890') -> // false
linksToAnotherPage('contact') -> // true
</code></pre>
<p>--</p>

<a href="#start-now">Start Now</a>
// links to another page
<a href="contact">Send Email</a>

<pre><code> function isInteractiveHref (href) {
return (
href.startsWith("mailto:") || href.startsWith("tel:") ||

)
}
isInteractiveHref(props.href) ? (

74,250,532 | <p><strong>Can you please help me change my code from current output to expected output?</strong> I am using apply() function of dataframe. It would be great if it could also be done more efficiently using vector operation.</p>
<p><strong>Current output:</strong></p>
<pre><code> col1 col2 serialno
0 100 0 4
1 100 100 0
2 100 100 0

3 200 100 5
4 200 200 5
5 300 200 6
6 300 300 6
</code></pre>
<p>My current code contains a static value (4). I need to increment it by one based on a condition (col1 != col2). In addition, I need to repeat the serial no for all rows that meet the condition (col1 == col2).</p>
<p><strong>My code:</strong></p>
<pre><code>import pandas as pd
columns = ['col1']
data = ['100','100','100','200','200','300','300']
df = pd.DataFrame(data=data,columns=columns)
df['col2'] = df.col1.shift(1).fillna(0)
print(df)
start = 4
series = (df['col1']!=df['col2']).apply(lambda x: start if x==True else 0)
df['serialno'] = series

74,250,570 | <p>I had a docker file that was working fine. However to remote debug it , I read that I needed to install <code>dlv</code> on it and then I need to run dlv and pass the parameter of the app I am trying to debug. So after installing dlv on it and attempting to run it. I get the error</p>
<pre><code>exec /dlv: no such file or directory
</code></pre>
<p>This is the docker file</p>
<pre><code> FROM golang:1.18-alpine AS builder
# Build Delve for debugging

CMD ["/dlv", "--listen=:40000", "--headless=true", "--api-version=2", "--accept-multiclient", "exec", "/app/fooapp"]
</code></pre>
<p>The above results in <code>exec /dlv: no such file or directory</code></p>
<p>I am not sure why this is happening. Being new to docker , I have tried different ways to debug it. I tried using <code>dive</code> to check and see if the image has <code>dlv</code> on it in the path <code>/dlv</code> and it does. I have also attached an image of it</p>

74,250,623 | <p>When creating elements using a loop and adding a class to them, should I first declare the variable outside the loop?</p>
<p>For example:</p>
<pre><code>const mainContainer = document.queryselector('.main-container');
const arr = [1,2,3,4,5];
arr.forEach((num)=> {
const newEl = document.createElement('div');
newEl.innerHtml = num;
mainContainer.appendChild(newEl);
newEl.addEventListener('click',()=> {
window.open('google.com')
})
})
</code></pre>
<p>This would open 5 new tabs, but the only way I can access the element is inside the loop, should I delare newEl outside the loop and just change it with let?</p>

74,250,675 | <p>I've been battling with a script to upload photos for user comments. Needless to say, I'm new to PHP. I have it so it confirms the file is an image and then continues to check its size. It's all working except when the image exceeds the size I've set. It does absolutely nothing. Here's my code:</p>
<pre class="lang-php prettyprint-override"><code>ini_set("display_errors",1);
error_reporting(E_ALL);
date_default_timezone_set('America/New_York');
$date = date('m-d-Y_h.i.s_a', time());
$target_path = "/home/SOME_USER/WEB/SOME_SITE/comment/uploading/uploads/";
$filename = $date. "_" .basename( $_FILES['uploadedfile']['name']);
$ext = pathinfo($filename, PATHINFO_EXTENSION);
$test = preg_replace('/\\.[^.\\s]{3,4}$/', '', $filename);
$newName = bin2hex($test);
$target_path = $target_path."". "$newName.".$ext;
if (is_uploaded_file($_FILES['uploadedfile']['tmp_name'])) {
$mime_type = mime_content_type($_FILES['uploadedfile']['tmp_name']);
$allowed_file_types = ['image/png', 'image/jpeg', 'image/gif'];
if (! in_array($mime_type, $allowed_file_types)) {
$url = "./index.php" . "?&message=Not an image";
header('Location: '.$url);
} else {
echo ('made it to this part ?');
return proceed();
}
}
function proceed() {
global $target_path;
global $newName;
global $ext;
echo 'made it here. . .';
if(isset($_FILES['uploadedfile']['name'])) {
if($_FILES['uploadedfile']['size'] > 3145728) { //3mb)
echo ('made it here #1');
$url = "./index.php" . "?&message=Too big !";
header('Location: '.$url);
} else {
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
$url = "./index.php" . "?&message=".$newName.".".$ext."";
header('Location: '.$url);
} else{
echo('Made it here');
$url = "./index.php" . "?&message=Too big !";
header('Location: '.$url);
}
}
}
}
</code></pre>
<p>I know the code is probably pretty ugly and could be written a lot better, and I'll work on that when I get it working properly, but I'm stuck here. Again, everything is working except when the image is too large and it does absolutely nothing on the upload script. I've added some mile markers for debugging like I would in Python but it doesn't seem to help in PHP.</p>
<p>Solved: In my <code>form</code> I had the file size limited to the same exact size as in my handler script. Changing the value in the <code>form</code> to just one byte larger fixed it.</p>

if (std::to_string(number).length() == 1)
cout << "Only one digit" << endl;
number = number / pow(10, (position - 1.0));
result = number % 10;
return result;
}
</code></pre>
<p>This is the code I currently have for the function. However, it outputs the number in reverse. How do I correct the digit position? I thought it didn't even function correctly until noticing it's in reverse order.</p>

74,250,873 | <p>Without reading the contents of a file into memory, how can I read "x" bytes from the file so that I can specify what x is for every separate read operation?</p>
<p>I see that the <code>Read</code> method of various <code>Reader</code>s takes a byte slice of a certain length and I can read from a file into that slice. But in that case the size of the slice is fixed, whereas what I would like to do, ideally, is something like:</p>
<pre><code>func main() {
f, err := os.Open("./file.txt")
if err != nil {
panic(err)
}
someBytes := f.Read(2)
someMoreBytes := f.Read(4)
}
</code></pre>
<p><code>bytes.Buffer</code> has a <code>Next</code> <a href="https://pkg.go.dev/bytes#Buffer.Next" rel="nofollow noreferrer">method</a> which behaves very closely to what I would want, but it requires an existing buffer to work, whereas I'm hoping to read an arbitrary amount of bytes from a file without needing to read the whole thing into memory.</p>
<p>What is the best way to accomplish this?</p>
<p>Thank you for your time.</p>

74,250,877 | <p>I have a random graph with 10 nodes where 4 nodes have the zero degree.</p>
<p>It is required to obtain the connected graph by 1) select a node with zero degree and a minimal feature (for exmaple, random number from uniform distribautin) corresponding to each edge and connect it with graph by creation two incident edges to the node and deleting the 3rd edge, 2) repeat step 1 for all zero degree nodes.</p>

74,250,887 | <p>I have a quick question.
The R code is as below.
When I want to run this code and enter a in textinput.</p>
<p>"query_db <- paste("select name, Votes,city from zomato_rest where name like '%",input$names,"%' and Votes <=", input$slider_votes,";")"</p>
<p>The result always only shows ' a '.
It won't show 'babb', 'accc' etc.</p>
<p>If I correct it as below and enter Roku, it shows no this data, but it exists in the dataset.
query_db <- paste("select name, Votes,city from zomato_rest where name = '",input$names,"' and Votes <=", input$slider_votes,";")</p>
<p>If I correct it again, it shows the data.
query_db <- paste("select name, Votes,city from zomato_rest where name ='Roku' and Votes <=", input$slider_votes,";")</p>
<p>Does anyone know the reason?</p>
<pre><code>library(shiny)
library(shinydashboard)
library(leaflet)
library(DBI)
library(odbc)
library(DT)
ui <- textInput("names", "Pattern of Name", "Please enter a name"),
actionButton("Go", "Get results!"),
DT::dataTableOutput("mytable")
)
server <- function(input, output,session) {
query_db <- paste("select name, Votes,city from zomato_rest where name like '%",input$names,"%' and Votes <=", input$slider_votes,";")
print(query_db)
data_db <- dbGetQuery(db, query_db)
</code></pre>
<p>output$mytable = DT::renderDataTable({
data_db
})</p>
<pre><code>
</code></pre>
<p>I want to see the result of code running in R same as the result running in SQL.
But, it looks like it always has space between the value and symbol => '% a %', so 'cbac' won't show up, but ' a ' shows up.</p>
<p>I expect it can show the result like '%a%', so 'cbac' shows up, but ' a ' won't show up.
I hope that I describe the situation clear enough.</p>

74,250,922 | <p>sorry for asking so soon again, this is my second project and I got stuck at this: I'm making a simple calculator with basic operations, and right now, I'm creating the buttons' functions so when they're pressed, the value of the button is input into the calculator screen; my problem is, that the button returns 'undefined', even though I think I'm targeting the right class using document.querySelectorAll().</p>

74,250,964 | <p>Hi I am creating a custom middleware in Django for the DRF.</p>
<p>So that when an user try to access any of the api the middleware will perform some operation and determine if the user is authorized to access the endpoint or not.</p>
<p>My code is like below:</p>
<pre class="lang-py prettyprint-override"><code>class PermissionMiddleware(MiddlewareMixin):
def process_view(self, request, view_func, view_args, view_kwargs):
if request.path.startswith('/admin/'):
return None
if request.path.startswith('/api/'):
is_allowed = True
if not is_allowed:
return # < -- What needs to return to block the access
return None
</code></pre>
<p>My problem is what should I return from the method for disallowing access to api? I can return None, if I want to give access. But I want to disallow access and return some message from the api view so that user knows that he is not allwed.</p>
<p>So in summery:</p>
<ol>
<li>What should I return from the middleware to block access?</li>
<li>How can I return message to user from the view that he is not authorized?</li>
</ol>
<p>Thanks</p>

74,251,126 | <p>I'm confused, I was asked to do a connection from Java into MySQL using OOP and DAO, but my professor asked us to do it in a the following way:</p>
<p>We need to make the variable "MethodOfPayment" as an int in Java and as a char in MySQL table, and we need to write the method of payment depending on the number you put in Java. For example:</p>
<p>Java: MethodOfPayment: (you write) 1 will insert "Credit card" in MySQL<br />
Java: MethodOfPayment: (you write) 2 will insert "Debit card" in MySQL<br />
but using the int MethodOfPayment variable.</p>
<p>I tried a switch, but it won't let me convert the int "With" letters to string, I don't even know if it's possible.</p>
<p>This is the insert I have in the DAO method class</p>
<pre><code>private static final String SQL_INSERT = "INSERT INTO Client(Name, LastName, MethodOfPayment ) VALUES (?,?,?)";
</code></pre>
<p>I do it with ResultSet, ArrayList, PreparedStatement with a JDBC connection to MySQL.</p>
<pre><code>public static int = MethodOfPayment;
</code></pre>
<p>This is the variable that will write on the database an the one my professor is asking us to keep as an int in java and write the char on MySQL.</p>
<p>This is the method I'm trying to convert the int to string, but obviously crashes because the letters inside the int. I don't know if it's possible or my professor is wrong.</p>
<pre class="lang-java prettyprint-override"><code>public static void PaymentMethod() {
int MethodSelection; //this is a variable to select the method in the switch and assign the values to the main variable of the payment
System.out.println("Insert Payment Method");
Scanner sc = new Scanner(System.in);
MethodSelection = Integer.parseInt(sc.nextLine());
switch (MethodSelection) {
case 1:
MethodOfPayment = Integer.parseInt("Debit");
break;
case 2:
MethodOfPayment = Integer.parseInt("Credit Card");
break;// ...
default:
System.out.println("Invalid Method, Try Again");
PaymentMethod(); // I don't know a way to restart the switch without restarting the whole method when another value is inserted
}
}
</code></pre>
<p>DAOmethod:</p>
<p>Person is the father clas with, name and Last name. I get TypeOfPayment from a son class that has get, set and stringbuilder with the super to get the person data</p>

74,251,177 | <p>Wondering, can hints work in PL SQL packages?</p>
<p>Recently, I have to tune a long-running query in a PLSQL package because it causes a "snapshot too old" issue. I got the query out of the package and tuned it individually. I used the required hints for my case to tune that query and its running time significantly decreased. But I am not sure whether hints work in PL/SQL package as well. Could please clarify whether they can work in PL/SQL packages or not?</p>
<p>Thanks in advance</p>

I want to be able to calculate a payment date schedule based on a set monthly payment date but to exclude exclude weekends and specific holiday dates e.g.
Here's My file I'm Working on:[<img src="https://i.stack.imgur.com/oMMNx.png" alt="It didn't let me upload the excel file." />].</p>
<p>Here is some function that I already used : <code>=IF(TEXT(O2,"dddd")=$U$2,O2+2,IF(TEXT(O2,"dddd")=$U$3,O2+1,O2))</code>This works for only weekends, It doesn't work on holidays, I want it to work not only on weekends and on holidays too.</p>

"""
print(type(datastring))#->str
</code></pre>
<p>My string is data than a read before from a file text, now I have that data in <code>datastring</code>.
In <code>datastring</code> always in the fourth line, the data is showed in the next way: <code>animalidAnimal[name="nameAnimal"</code></p>
<p>So I would like to code a function that takes as a parameter a string like above, and return the part of <code>idAnimal</code> of the first line that starts in the following way: <code>animalidAnimal[name="nameAnimal"</code>
So for example in the first string my expected output would be:</p>
<pre><code>ko5854hg
</code></pre>
<p>Other example:</p>
<pre><code>datastring = """
Animals {
idAnimal
nameAnimal
animal456jlk165ut[name="Dalty"]
animal6ljkj[name="Moon"]
}
</code></pre>
<p>Expected output:</p>
<pre><code>456jlk165ut
</code></pre>
<p>Last example:</p>
<pre><code>datastring = """
Animals {

animalko5854hg[name="David"]
animalko5854hg[name="Oty"]
animalko5854hg[name="Dan"]
}
</code></pre>
<p>Expected output:</p>
<pre><code>k45lil69lhfr5942lk
</code></pre>
<p>I don´t want to be considered as a lazy person, but I don´t really know how to start coding that, I read about <code>startswith</code> and <code>endswith</code> functions, but those only return <code>True/False</code> values.</p>
<p>Thanks.</p>

74,251,305 | <p>I'd like to set datagrid cell background colour based on its value</p>
<p>What I understand is normally, I would need to create a class
Then { get: set: } data property, bind data collection to datagrid itemsource, finally use datatrigger to set background color</p>
<p>However, in my scenario, data is dynamic instead of static from column 4
(starting from column 'Data001' in below example screenshot)</p>
<p>Which means,</p>
<ol>
<li>number of columns is dynamic;</li>
<li>column header name is dynamic;</li>
</ol>
<p><a href="https://i.stack.imgur.com/mvO7u.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mvO7u.png" alt="enter image description here" /></a></p>
<p>So I didn't end up creating data class, instead I put data into a dictionary first</p>
<p>And then from dictionary into datatable, convert datatable into dataview and finally bind to ItemsSource.</p>
<p>Something like below:</p>
<pre class="lang-cs prettyprint-override"><code>//viewModel
var dtCalcResult = new DataTable();
DtView = dtCalcResult.AsDataView();
//xaml
<DataGrid
x:Name="dtgdTest"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Margin="10"
ItemsSource="{Binding DtView}"
RowHeight="16"
FrozenColumnCount="3"
ColumnHeaderHeight="24"
EnableRowVirtualization="True"
EnableColumnVirtualization="True"
Loaded="dtgdTest_Load"
>
</code></pre>
<p>Now my question is how to assign cell background colour by its value?</p>
<p>I have tried to work with the following way -></p>
<p>Use GetCellContent() to get cell value, then set background colour base on value</p>
<p>Something like this:</p>
<pre class="lang-cs prettyprint-override"><code> // GET ROW COUNT
var rowCount = targetDataGrid.Items.Count;
for (int i = 0; i < rowCount; ++i)
{
// GET ROW OBJECT
var row = targetDataGrid.ItemContainerGenerator.ContainerFromIndex(i) as DataGridRow;
if (row == null)
{
// USE ScrollIntoView() TO THAT ROW
targetDataGrid.UpdateLayout();
targetDataGrid.ScrollIntoView(targetDataGrid.Items[i]);
// TRY TO GET OBJECT AGAIN
row = targetDataGrid.ItemContainerGenerator.ContainerFromIndex(i) as DataGridRow;
}
// GET COLUMN COUNT
var columnCount = targetDataGrid.Columns.Count;
for (int j = 0; j < columnCount; ++j)
{
// GET CELL OBJECT
var elem = targetDataGrid.Columns[j].GetCellContent(row);
if (elem == null)
{
// USE ScrollIntoView() TO THAT COLUMN
targetDataGrid.UpdateLayout();
targetDataGrid.ScrollIntoView(targetDataGrid.Columns[j]);
// TRY TO GET OBJECT AGAIN
elem = targetDataGrid.Columns[j].GetCellContent(row);
}
// SET BACKGROUND COLOUR
DataGridCell cell = elem.Parent as DataGridCell;
string colHeader = targetDataGrid.Columns[j].Header.ToString();
string cellData = _viewModel.DictColNameAndValues[colHeader][i];
//float actHour = _viewModel.DictValueLists_ActHour[colHeader][i];
if (8 < float.Parse(cellData))
{
cell.Background = Brushes.Green;
}
else
{
cell.Background = Brushes.White;
}
</code></pre>
<p>With above, the result is:</p>
<ol>
<li>Getting error, after ScrollIntoView(), still cannot get cell value, returns null;</li>
<li>While cells without an error, background colour assignment is wrong; (like colour appears to incorrect cells)</li>
<li>Once I scroll in view, the assigned colour will shift position;</li>
<li>When I load ~1k+ columns, pagination becomes super slow and lag (I felt this one probably need to create a separate thread to ask)</li>
</ol>
<p>Something like this:
<a href="https://i.stack.imgur.com/kmKuS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kmKuS.png" alt="enter image description here" /></a></p>
<p>If datagrid is not the best way to do this, is there any other user control or method to archive my goal? (to be able to assign cell background colour when having dynamic columns)</p>
<p>I can give it a try if there's any as long as the package license is free to publish</p>
<p>Thanks!</p>
<hr />
<p><em>2022-Oct30 Update</em></p>
<p>Follow up question to @Siegfried.V answer:</p>
<p>Here hopefully I made a better example which closer to my real scenario:</p>

<p>It can show that starting from column-4, column names are all dates</p>
<p>The range of dates is also going to be dynamic populated depending on the data source pulled each time. Which means I cannot bind with any static properties unlike first three columns(Name, Pref and Age)</p>

74,251,314 | <p>Next.js 13 is out. One of the refactored components is <code>next/image</code>.</p>
<p>I want to use it, but I want to set the image size using tailwind.</p>
<p>Here's my code:</p>
<pre><code>import Image from 'next/image'
const Index = () => {
return (
<div>
<Image
src="https://picsum.photos/800/600"
layout="fill"
className="w-48 aspect-square md:w-72 xl:w-48"
/>
</div>
)
}
</code></pre>
<p>And I get this error:</p>
<blockquote>
<p>Error: Image with src "https://picsum.photos/800/600" is missing required "width" property.</p>
</blockquote>
<p>However, in <a href="https://nextjs.org/docs/basic-features/image-optimization#image-sizing" rel="nofollow noreferrer">docs</a> it's said that it's possible to use <code>fill</code> without specifying the <code>width</code> and <code>height</code>.</p>
<p>What do I miss here?</p>

74,251,319 | <p>I've been learning for 10 days, this is my 1st mini project, I'm asked to build a log in system for employees and 1 admin, with each having a simple menu with multiple options. I must create a txt file with 10 employees each with different charact(id, username, salary..). The employee should enter a username and leave password empty but admin should enter predefined username and password with only 5 wrong attempts allowed. but its not working as intended for admin, when I enter wrong password, it just goes for 5 attempts and state that password limit reached.</p>
<pre><code>with open('data.txt') as f:
data = f.readlines()
dict = {}
for r in data:
fields = r.split(",")
id = fields[0]
username = fields[1]
date = fields[2]
gender = fields[3]
salary = fields[4]
dict[username] = {"id": id, "name": username, "date of joining": date, "gender": gender, "salary": salary}#use username as primary key since it is what employee use to log in
def log_in(username,password):
if username in dict.keys() and password=="":

74,251,408 | <p>I have been dealing with this problem many times and after reading different articles, I still dont know which is the best approach</p>
<p>Lets say I have this model:</p>
<p>-Author
-Category
-Book</p>
<p>A book cannot exists without an author and a category, so when talking about a post endpoint for a creating a new book, I have fouroptions:</p>
<ol>
<li><p>myapi/v1/authors/{authorId}/category/{categoryId}/boooks (nesting entities)</p>
</li>
<li><p>myapi/v1/{authorId}/{categoryId}/boooks (just the foreign keys as path parameters)</p>
</li>
<li><p>myapi/v1/books/?author={authorId}&category={categoryId} (using query params)</p>
</li>
<li><p>myapi/v1/books (using a request DTO containing both author and category id)</p>
</li>
</ol>
<p>Which one of these options is the best? Option 1 gives a lot of information about the relations, but it can be difficult to mantain as relationships grow (very long URI)</p>
<p>Options 2 and 3 looks fine to me, but I dont know if it is the proper approach</p>
<p>Option 4 is easier to read and mantain, but it does not provide information about how book i related to author and category</p>
<p>I am open to advice. Thanks!</p>

74,251,511 | <p>I am writing discord bot on python (discord.py). This bot for many servers and I want to make cooldown system. This looks like this:
User uses command on the first server and if he uses it again, bot will tell user that command on cooldown, but if user will go to the second server, command will work without cooldown that is on the first server.</p>

74,251,556 | <p>I'm currently trying to parse <a href="https://easyupload.io/8nncki" rel="nofollow noreferrer">excel files</a> that contain somewhat structured information. The data I am interested in is in a subrange of an excel sheet. Basically the excel contains key-value pairs where the key is usually named in a predictable manner (found with regex). Keys are in the same column and the value pair is on the right side of the key in the excel sheet.</p>
<p>Regex pattern <code>pattern = r'[Tt]emperature|[Ss]tren|[Cc]omment' </code> predictably matches the keys. Therefore if I can find the column where the keys are located and the rows where the keys are present, I am able to find the subrange of interest and parse it further.</p>
<p>Goals:</p>
<ol>
<li>Get list of row indices that match regex (e.g. <code>[5, 6, 8, 9]</code>)</li>
<li>Find which column contains keys that match regex (e.g. <code>Unnamed: 3</code>)</li>
</ol>
<p><a href="https://i.stack.imgur.com/hevO8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hevO8.png" alt="Image of original excel" /></a></p>
<p>When I read in the excel using <code>df_original = pd.read_excel(filename, sheet_name=sheet)</code> the dataframe looks like this</p>
<pre><code>df_original = pd.DataFrame({'Unnamed: 0':['Value', 'Name', np.nan, 'Mark', 'Molly', 'Jack', 'Tom', 'Lena', np.nan, np.nan],
'Unnamed: 1':['High', 'New York', np.nan, '5000', '5250', '4600', '2500', '4950', np.nan, np.nan],
'Unnamed: 2':[np.nan, np.nan, np.nan, np.nan, np.nan, np.nan, np.nan, np.nan, np.nan, np.nan],
'Unnamed: 3':['Other', 125, 127, np.nan, np.nan, 'Temperature (C)', 'Strength', np.nan, 'Temperature (F)', 'Comment'],

<p>What is the easiest way to solve Goal 2? Basically I want to find columns that contain at least one value that matches the regex pattern. The wanted output would be <code>[Unnamed: 5]</code>. There may be some easy way to solve goals 1 and 2 at the same time. For example:</p>
<pre><code>col_of_interest = 'Unnamed: 3' # <- find this value
col_range = df_original.columns[df_original.columns.to_list().index(col_of_interest): ]
print(col_range)
Index(['Unnamed: 3', 'Unnamed: 4', 'Unnamed: 5', 'Unnamed: 6'], dtype='object')
target = df_original.loc[row_range, col_range]
display(target)

74,251,563 | <p>Because I am dealing with an environment with certain memory constraints, I need to allocate a very large statically sized array at the beginning of my program's execution:</p>
<pre><code>let mut data: [Foo; 1024] = ?
</code></pre>
<p>How can I initialize this array with "empty" data?</p>
<p>I have tried using the <code>default</code> method, since <code>Foo</code> also has a default:</p>
<pre><code>let mut data: [Foo; 1024] = Default::default(),
</code></pre>
<p>but it doesn't work, because <code>array</code> only implements default for a fixed set of sizes:</p>
<pre><code>error[E0277]: the trait bound `[foo::Foo; 1024]: std::default::Default` is not satisfied
--> /src/foo.rs:143:22
|
143 | = Default::default(),
| ^^^^^^^^^^^^^^^^ the trait `std::default::Default` is not implemented for `[foo::Foo; 1024]`
|
= help: the following other types implement trait `std::default::Default`:
&[T]
&mut [T]
[T; 0]
[T; 10]
[T; 11]
[T; 12]
[T; 13]
[T; 14]
and 27 others
</code></pre>
<p>How can I initialize such a large statically sized array without typing a giant literal in my code?</p>

<p>This code loops thru each server printing out what its doing.</p>

74,251,602 | <p>For example, <code>most_average([1, 2, 3, 4, 5])</code> should return 3 (the average of the numbers in the list is 3.0, and 3 is clearly closest to this).
<code>most_average([3, 4, 3, 1])</code> should also return 3 (the average is 2.75, and 3 is closer to 2.75 than is any other number in the list).</p>

result = sum / len(numbers)

74,251,728 | <p>I am working with a React project and I was trying to add a content after I clicked on a link to show that it's active, but it keeps popping out that bug. Is there any way I can fix this?</p>
<p>This is my code below:</p>
<pre><code>const activeClassName =
'relative before:content-[' *
'] before:-top-4 before:left-1/2 before:-ml-1 before:absolute before:text-amber-400'

74,251,780 | <p>I have 2 tables connected with each other, for simplicity lets say ID of the 1st is connected to UserCreated_FK of the 2nd table.</p>
<p>Table A:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>ID</th>
<th>NAME</th>
</tr>
</thead>
<tbody>
<tr>
<td>237</td>
<td>Gal</td>
</tr>
<tr>
<td>240</td>
<td>blah</td>
</tr>
<tr>
<td>250</td>
<td>blah2</td>
</tr>
</tbody>
</table>
</div>
<p>in the parallel table ( aka table B ) I have the following:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>UserCreated_FK</th>
<th>col2</th>
</tr>
</thead>
<tbody>
<tr>
<td>237</td>
<td>10/10</td>
</tr>
<tr>
<td>20 more rows of 237</td>
<td>20 more rows of 237</td>
</tr>
<tr>
<td>240</td>
<td>11/10</td>
</tr>
<tr>
<td>5 more rows of 240</td>
<td>20 more rows of 240</td>
</tr>
<tr>
<td>250</td>
<td>12/10</td>
</tr>
<tr>
<td>14 more rows of 250</td>
<td>20 more rows of 250</td>
</tr>
</tbody>
</table>
</div>
<p>Result wanted:
id.237 x10 last(might be sorted by date col I have).</p>
<p>no 240 (cause less than 10).</p>
<p>id.250 x10 last records(might be sorted by date col I have).</p>
<p>My task is to check which of those IDs(person'sIds) have more then 10 records on table B ( because table A is just the ids and names not the actual records of them.</p>
<p>So for example, ID no.237 got 19 records on table B I want to be able to pull the last 10 records of that user.</p>
<p>And again, the condition is only users that have more than 10 records, then to pull the last of 10 of those..</p>
<p>Hope I was understandable, thanks a lot, any help will be appreciated!</p>

<p>In above output vertical months are registered users count and horizontal rows are their activity.</p>
<p>Example:</p>
<p>In vertical January month 1563 users are registered, in same row horizontal January has 1563 because registration will count as their activity. In same row July month 13 users are active out of 1563 registered users and same goes on for other months of same row.</p>
<p>I'm getting values in expected tds but want to remove extra generated td (Marked in red box).</p>

<p>The only success I've had is getting Powershell to show the full JSON. Converting the JSON to a hashtable causes its key-value information to drop, and for some reason I cannot get nested foreach or a recursive functions to drill into the JSON structure. I had the most promise with the recursive function, but it kept reporting back Header and Data as the results, it never even drilled down to the second layer.</p>

74,252,001 | <p>A few months ago I had a job interview test where I was asked to code an interface that functions like an online personality test using HTML5, CSS, and Javascript.</p>
<p>This simple online test will display one question at a time, with the answer options at the bottom. When the user clicks on one of the answers, it will move on to display the next question. The answer selected will be stored in a JS array to be submitted at the end of the test.</p>
<p>The interface will prompt user questions with answer options, upon answering, the next question will show. Upon every new test, the questions should randomize their order.</p>
<p>The body of my HTML looks like this:</p>
<pre><code><div class="panel">
<div class="question-container" id="question">
<h1>Question goes here</h1>
</div>
<div class="option-container">
<button type="button" class="option next" id="op1">Option 1</button>
<button type="button" class="option next" id="op2">Option 2</button>
</div>
<div class="navigation">
<p><span id="numbers">0</span> of 5 questions completed.</p>
</div>
</div>
</code></pre>
<p>My JS code looks like this:</p>
<pre><code>const Questions = [{
id: 0,
q: "I value",
a: ["justice", "mercy"],
}, {
id: 1,
q: "A quiet weekend at home is",
a: ["boring", "rejuvenating"],
}, {
id: 2,
q: "I prefer speakers that communicate",
a: ["literally", "figuratively"],
}, {
id: 3,
q: "With people, I am more often",
a: ["brief and to the point", "friendly and warm"],
}]
const Answers = []
var start = true;
function iterate(id){
// Test get text
console.log(Questions[id].q);
console.log(Questions[id].a[0]);
console.log(Questions[id].a[1]);
// Getting the question
const question = document.getElementById("question");
const numbers = document.getElementById("numbers");
// Setting the question text
question.innerText = Questions[id].q;
numbers.innerText = Questions[id].id;
// Getting the options
const op1 = document.getElementById("op1");
const op2 = document.getElementById("op2");
// Providing option text
op1.innerText = Questions[id].a[0];
op2.innerText = Questions[id].a[1];
}
if (start) {
iterate(0);
}
// Next button and method
const next = document.getElementsByClassName('next')[0];
var id = 0;
next.addEventListener("click", () => {
start = false;
if (id < 4) {
id++;
iterate(id);
console.log(id);
} else {
// Mark the test as finished
Questions.innerText = "Congratulations. You have finished your personality assessment test"
op1.innerText = "Option 1";
op2.innerText = "Option 2";
}
})
</code></pre>
<p>However, I am having a problem when trying to run the code, the interface cannot display any questions or answers, only the initial texts set by the static HTML file (Question goes here, Option 1, Option 2). In addition, I opened the Inspect tool on the browser, which the console produces the following error message:</p>
<blockquote>
<p>Uncaught TypeError: Cannot set properties of null (setting 'innerText')
at iterate (script.js:38:24)
at script.js:57:5</p>
</blockquote>
<pre><code>question.innerText = Questions[id].q;
</code></pre>
<p>If anyone is having the same problem and is expertise in JavaScript and front-end development, please provide a solution to solve the errors.</p>
<p>I have tried to code the online test interface with the given sample questions and answers according to the JavaScript standards and references from similar codes and projects. However, it did not work out and the questions and answers do not display on the interface.</p>

74,252,043 | <p>Using Regex, I want to remove all hyphens only from specific quoted words in a text file.</p>
<p>Scenario: This is from code where I need to remove hyphens from Json property names before the Json string is deserialized using a JsonConstructor (<strike>which does not honor JsonPropertyName attributes</strike> <em><strong>see edit below</strong></em>).</p>
<p>Example list of words which need hyphens removed (quotes should be part of the match):</p>
<pre><code>"monthly-amount"
"annual-amount"
"ask-for-shipping-address"
</code></pre>
<p>Example input Json:</p>
<pre><code>{
"id": "b9d7574f-5246-4c94-ade5-1d4e9b169afc",
"name": "James-John Moonly-Batcher"
"monthly-amount" : 2000,
"annual-amount" : 12000,
"ask-for-shipping-address" : false
}
</code></pre>
<p>Expected output Json:</p>
<pre><code>{
"id": "b9d7574f-5246-4c94-ade5-1d4e9b169afc",
"name": "James-John Moonly-Batcher"
"monthlyamount" : 2000,
"annualamount" : 12000,
"askforshippingaddress" : false
}
</code></pre>
<p>Note that in the example, hyphens in the name and id values are not removed.</p>
<p>I understand how I can match the words in the list. What I don't understand is how I can then use the matched word and replace all hyphens in it.</p>
<p>Alternatively, if a regex can be constructed that works without the word list which can replace hyphens in any property name (but not in property values), that would also be welcome.</p>
<p>I would love to receive some input on this task before the little hair I have left is being scratched off my head.....</p>
<p><strong>EDIT:</strong></p>
<p>Only after I successfully applied the accepted answer did I realize that my initial problem was an entirely different one: wrong parameter names of the class constructor for deserialization (JSON constructor).</p>
<p>I had misunderstood the <a href="https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json/immutability?pivots=dotnet-6-0" rel="nofollow noreferrer">docs</a> about how parameter names of a JsonConstructor need to be, thinking that the parameter names of the JSON constructor need to match the names in the JSON, whereas in reality, the parameter names of the JSON constructor need to match the actual property names of the C# class (case insensitive). By matching the property names of the C# class, the deserializer can find the JsonPropertyName attribute corresponding to the constructor parameter name, and thus it can find the JSON names to look for.</p>
<p>So with the correct parameter names in place, there is no need to alter Json property names in the first place.</p>
