<p>I'm trying to associate in a dataframe the values of a list of numbers with the respective strings. Here's the problem:</p>
<pre><code>import pandas as pd
categories = {"key1":["string1", "string2", "string3"], "key2": ["string1", "str1", "str2"]}
strings= ["string1", "string2", "string3", "string1", "str1", "str2"]
numbers = [1,2,3,4,5,6]
array = []
expected_fields = []
#Creation of the dataframe with double rows, where the first is the key of categories
#and the second is the elements of the list present in the values of categories
for key, value in categories.items():
array.extend([key]* len(value))
expected_fields.extend(value)
arrays = [array ,expected_fields]
#Creation of the dataframe
tuples = list(zip(*arrays))
index = pd.MultiIndex.from_tuples(tuples)
df = pd.Series(dtype='float', index=index)
for key, values in categories.items():
for value in values:
for i in range(len(strings)):
if strings[i] == value:
df[key, value] = numbers[i]
print(df)
</code></pre>
<p>Output:</p>
<pre><code>key1 string1 4.0 <---------
string2 2.0
string3 3.0
key2 string1 4.0
str1 5.0
str2 6.0
</code></pre>
<p>Expected output:</p>
<pre><code>key1 string1 1.0 <---------
string2 2.0
string3 3.0
key2 string1 4.0
str1 5.0
str2 6.0
</code></pre>
<p>The association is always going for the last element of the list due to the repeated string in strings. However I want the first element of numbers for the first repeated string and the following number for the second repeated string.</p>
<p>I could count the number of elements of the values of the dictionary categories for each key and perform an increment in the for loop correspondent to the strings and based on the lower and upper limit add an if inside that for loop, however I can't go for this approach due to technical limitations.</p>

<p>populate each hand with two cards. Take a card from the deck
and put it in the player_hand list. Then, take a card from the deck and
put it in the dealer_hand list. Do that one more time in that order so that the dealer and player have each two cards. Make sure the dealer's first card is face down. I keep receiving this error from my 2 tests.</p>

<p>I am trying to grab data from JSON file based on what quarter the dates represent. My goal is to assign the data to a variable so I should have Q1, Q2, Q3, Q4 variables holding the data inside. Below is the JSON:</p>
<pre><code>{
"lastDate":{
"0":"2022Q4",
"1":"2022Q4",
"2":"2022Q4",
"7":"2022Q4",
"8":"2022Q4",
"9":"2022Q4",
"18":"2022Q3",
"19":"2022Q3",
"22":"2022Q3",
"24":"2022Q2"
},
"transactionType":{
"0":"Sell",
"1":"Automatic Sell",
"2":"Automatic Sell",
"7":"Automatic Sell",
"8":"Sell",
"9":"Automatic Sell",
"18":"Automatic Sell",
"19":"Automatic Sell",
"22":"Automatic Sell",
"24":"Automatic Sell"
},
"sharesTraded":{
"0":"20,200",
"1":"176,299",
"2":"8,053",
"7":"167,889",
"8":"13,250",
"9":"176,299",
"18":"96,735",
"19":"15,366",
"22":"25,000",
"24":"25,000"
}
}
</code></pre>
<p>Now if i try to use the following code:</p>
<pre><code>import json
data = json.load(open("AAPL22data.json"))
Q2data = [item for item in data if '2022Q2' in data['lastDate']]
print(Q2data)
</code></pre>
<p>My ideal output should be:</p>
<pre><code>{
"lastDate":{
"24":"2022Q2"
},
"transactionType":{
"24":"Automatic Sell"
},
"sharesTraded":{
"24":"25,000"
}
}
</code></pre>
<p>And then repeat the same structure for the other quarters. However, my current output gives me "[ ]"</p>

<p>world!
I'm currently stuck on this problem where i want to join two columns and run the select statement of the two, but i'm getting errors; these are the columns i want to join:</p>
<pre><code>SELECT DISTINCT column_name FROM owner_name.table_name ORDER BY column_name;
</code></pre>
<p>and</p>
<pre><code>SELECT DISTINCT * FROM (SELECT count(column_name) OVER (partition by column_name) Amount from owner_name.table_name order by column_name);
</code></pre>
<p>where in the second, for every row, i count how many equal rows i have for each value.</p>
<p>the two columns values:
<a href="https://i.stack.imgur.com/FMe2M.png" rel="nofollow noreferrer">first column</a>
<a href="https://i.stack.imgur.com/BbZC1.png" rel="nofollow noreferrer">second column</a></p>
<p>i dont know how to have both of them next to each other as a normal select statement:
SELECT column_1, column_2 FROM table;</p>

<h2><strong>Problem</strong></h2>

<p>I have two dataframes:</p>
<pre><code>df1 =
C0 C1. C2.
4 AB. 1. 2
5 AC. 7 8
6 AD. 9. 9
7 AE. 2. 6
8 AG 8. 9
df2 =
C0 C1. C2
8 AB 0. 1
9 AE. 6. 3
10 AD. 1. 2
</code></pre>
<p>I want to apply a subtraction between these two dataframes, such that when the value of the columns C0 is the same - I will get the subsraction, and when is not - a bool column will have the value False. notice that current indeics are not aligned.
So new df1 should be:</p>
<pre><code>df1 =
C0 C1. C2. diff_C1 match
4 AB. 1. 2. 1. True
5 AC. 7 8. 0. False
6 AD. 9. 9. 8. True
7 AE. 2. 6. -4. True
8 AG 8. 9. 0 False
</code></pre>
<p>What is the best way to do it?</p>

<p>I have in a component this piece of code</p>
<p><a href="https://i.stack.imgur.com/RAwmk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RAwmk.png" alt="enter image description here" /></a></p>
<p>TagCanvas is defined in the _app.tsx file within a legacy JS script. I need to do like that because if I include it in the component using it doesn't work when the component is rendered again.</p>
<p><a href="https://i.stack.imgur.com/m83xv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/m83xv.png" alt="enter image description here" /></a></p>
<p>I want to test this component, so I have started rendering the component like this:</p>
<pre><code>import {render, screen} from '@testing-library/react';
import {MusasCloud} from '../../../components/MusasCloud.tsx';
const TagCanvas = jest.fn();
describe('MusasCloud component', () => {
test('Should render the MusasCloud component', () => {
render(<MusasCloud musas={[]} />);
screen.debug();
});
});
</code></pre>
<p>I get the html rendered as I expect but I am getting the Canvas error which I would like to avoid.</p>
<p><a href="https://i.stack.imgur.com/t4Udw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/t4Udw.png" alt="enter image description here" /></a></p>
<p>As you can see I have tried to mock the TagCanvas function using <code>jest.fn()</code> but this is not ding the job I'd expect.</p>
<p><strong>Question</strong>: How can I avoid this exception when running the test?</p>

<p>I have code to generate series of keys as in below:</p>
<pre><code>def Keygen (x,r,size):
key=[]
for i in range(size):
x= r*x*(1-x)
key.append(int((x*pow(10,16))%256))
return key
if __name__=="__main__":
key=Keygen(0.45,0.685,92)#Intial Parameters
print('nx key:', key, "\n")
</code></pre>
<p>The output keys are:</p>
<pre><code>nx key: [0, 11, 53, 42, 111, 38, 55, 102, 252, 155, 54, 219, 149, 220, 235, 177, 140, 46, 209, 249, 46, 241, 218, 243, 6, 166, 247, 106, 33, 24, 220, 185, 129, 182, 214, 210, 180, 28, 84, 117, 228, 213, 205, 240, 125, 37, 181, 234, 246, 54, 22, 195, 38, 174, 212, 166, 9, 237, 25, 225, 81, 23, 244, 235, 171, 196, 111, 182, 227, 26, 22, 246, 35, 52, 225, 249, 90, 237, 162, 111, 76, 52, 35, 24, 16, 11, 7, 5, 3, 2, 1, 1]
</code></pre>
<p>I try to convert all key values to hex by used the following code:</p>
<pre><code>K=hex(key)
print('nx key:', key, "\n")
</code></pre>
<p>But when run I got the error "TypeError: 'list' object cannot be interpreted as an integer" </p>
<p>Then try to use "K= hex(ord(key))" but also got another error "TypeError: ord() expected string of length 1, but list found"</p>
<p>What I need is to convert all keys to hex, then select just 4 keys to be like this </p>
<pre><code>K = (0x3412, 0x7856, 0xBC9A, 0xF0DE)
</code></pre>

<p>I have setup a wagtail website. It works great for postings like a blog and simply add new pages.
But what if I want to add some extra functions to a page. Like showing values from my own database in a table.
Normally i use a models.py, views.py and template.py. But now I don’t see any views.py to add functions or a urls.py to redirect to an url?</p>
<p>Don’t know where to start!
Or is this not the meaning of a wagtail site, to customize it that way?</p>
<p>Thnx in advanced.</p>

<p>New to C here, I am creating an insert function that will insert any value to an array provided I give the position of the array.</p>
<p>For example, here is what I have tried:</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
int insert(int A[], int N, int P, int KEY){
int i = N - 1;
while(i >= P){
A[i+1] = A[i];
i += 1;
}
A[P] = KEY;
N = N+1;
return *A;
}
int main(void){
int arr[5] = { 1, 2, 3, 4, 5 };
size_t n = sizeof(arr)/sizeof(arr[0]);
int p = 3;
int K = 2;
int result;
result = insert(arr, n, p, K);
printf("Insert values: %d", result);
return 0;
}
</code></pre>
<p>However, I get the following error:</p>
<blockquote>
<p>zsh: segmentation fault ./insert</p>
</blockquote>

<h1>Problem</h1>
<p>First off, I am going to clarify that this question is not a duplicate of <a href="https://stackoverflow.com/questions/2536379/difference-in-months-between-two-dates-in-javascript">Difference in months between two dates in javascript</a> or <a href="https://stackoverflow.com/questions/4312825/javascript-month-difference?noredirect=1&lq=1">javascript month difference</a></p>
<p>My question is specifically about getting the <em>months</em> in between two dates, not the <em>number</em> of months.</p>
<h1>Expected Results</h1>
<p>So If <code>date1</code> is 11/01/2022 (mm/dd/yyyy) and <code>date2</code> is 02/20/2023, it should output an array of months including the month of <code>date1</code> and <code>date2</code> like <code>["November", "December", "January", "February"]</code>. I need to know how to return the actual months between two dates, not the number of months. Can somebody explain what would be the way to do that?</p>

<p>I am trying to use the <code>@Valid</code> and <code>@NotBlank</code> annotations in my spring boot project within IntelliJ IDEA 2022.2.3 (Community Edition)
Build #IC-222.4345.14, built on October 5, 2022</p>
<p>I have added dependency like below in my project pom.xml</p>
<pre><code><dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
<scope>test</scope>
</dependency>
</code></pre>
<p>In my entity class i have added <code>@NotBlank</code> annotation as below</p>
<pre><code>@NotBlank(message = "Please add the department name")
private String departmentName;
</code></pre>
<p>In my controller class i have added <code>@Valid</code> annotation as well</p>
<pre><code>@PostMapping("/departments")
public Department saveDepartment(@Valid @RequestBody Department department)
{
return departmentService.saveDepartment(department);
}
</code></pre>
<p>Even with all this i don't think the validation APIs are working.</p>
<p>My spring boot version is</p>
<pre><code><parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.5</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
</code></pre>
<p>Ideally i should be getting validation error if i don't pass the department name in my POST request BUT i never get any error with blank department name where my annotations are present.</p>
<p>I have tried various suggested solutions like closing and restarting IntelliJ Idea, Rebuilt the project. Also, I have tried invalidating the cache. NOTHING IS WORKING !!! The dependencies also seem to be all GOOD.</p>
<p>What else I could try?</p>

<p>So I am working on an online shop as a practice
I have imported products data and wanna make pagination. On a page it will be 12 products like so
<a href="https://i.stack.imgur.com/hxxmw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hxxmw.png" alt="enter image description here" /></a></p>
<p>I have this kind of code, but I don't understand why there is an infinite loop in useEffect and how to fix this
The error is: "Maximum update depth exceeded. This can happen when a component calls setState inside useEffect, but useEffect either doesn't have a dependency array, or one of the dependencies changes on every render."
I can rid of products in dependancy, but not sure it's the way</p>
<pre><code>import React, {useState, useEffect} from "react";
import data from './products.json'
import Product from "./components/Product/Product";
const PRODUCTS_PER_PAGE = 12
export const Shop = () => {
const [products, setProducts] = useState(data.products)
const [currentPage, setCurrentPage] = useState(1)
const firstIndex = (currentPage - 1) * PRODUCTS_PER_PAGE
const lastIndex = firstIndex + PRODUCTS_PER_PAGE
const totalPages = products.length / PRODUCTS_PER_PAGE
useEffect(() => {
const slicedProducts = products.slice(firstIndex,lastIndex)
setProducts(slicedProducts)
console.log(slicedProducts)
}, [currentPage, products])
return (
<div className="products">
{
products.map((product) => (
<Product product={product}/>))
}
</div>
)
}
</code></pre>

<p>I have a script that uses ts-node:</p>
<pre><code>#!/usr/binenv ts-node
const top: number[] = [];
</code></pre>
<p>but <code>tsc</code> complains:</p>
<pre><code>top3.ts(3,7): error TS2451: Cannot redeclare block-scoped variable 'top'.
</code></pre>
<p>because apparently <code>top</code> is a global variable in browsers.</p>
<p>I've installed <code>@types/node</code> and my <code>tsconfig.json</code> reads:</p>
<pre><code>{
"compilerOptions": {
"noImplicitAny": true,
"target": "es6",
"types": ["node"],
}
}
</code></pre>
<p>so I can refer to node builtins like <code>process</code>.</p>
<p>How do I configure <code>tsc</code> so that it does not include browser builtins, but only pure ECMAScript + node.js builtins?</p>

<p>I have recently explored handling JSON data with the org.json library and all went well.
Now I started a bigger Maven project, for which I intend to use the Jackson libraries in stead.
Sadly, it does not seem to work for me. I wanted to try out the ObjectMapper class, that VScode autocompleted for me, which also automatically adds the required import:</p>
<pre><code>import com.fasterxml.jackson.databind.ObjectMapper;
</code></pre>
<p>However, I also immediately get an error on that line:
"<strong>The type com.fasterxml.jackson.databind.ObjectMapper is not accessible Java (16778666)</strong>"</p>
<p>I have added the necessary dependencies to my pom.xml file like so:</p>
<pre><code><dependencies>
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-controls</artifactId>
<version>13</version>
</dependency>
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-fxml</artifactId>
<version>13</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.14.0</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.14.0</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.14.0</version>
</dependency>
</dependencies>
</code></pre>
<p>Am I missing something? Are there any other steps that I should have taken?</p>

<p>I would like to know if there is a faster way to print all the not empty elements of a string list in Java.</p>
<p>Currently, this is my code and it works, but I would like to know if there is another, shorter way to do it. That means without creating a "cloned list" from which we removed all the empty element (as we must not edit the original list "strings")</p>
<pre><code>List<String> strings = Arrays.asList("abc", "", "bc", "efg", "abcd", "", "jkl");
//get count of empty string
int countEmptyStr = (int) strings.stream().filter(string -> string.isEmpty()).count();
System.out.println("Number of empty strings:" + countEmptyStr );
//get count of no empty string
int countNoEmptyStr = (int) strings.stream().filter(string -> !string.isEmpty()).count();
System.out.println("Number of no-empty strings:" + countNoEmptyStr );
//print only no empty string from the list
List<String> stringsRmvd = new ArrayList<String>(strings);
stringsRmvd.removeAll(Arrays.asList("", null));
System.out.println("Print only no empty string from the list:" + stringsRmvd);
</code></pre>
<p>And we get in the output (as expected):</p>
<pre><code>Number of empty strings:2
Number of no-empty strings:5
Print only no empty string from the list:[abc, bc, efg, abcd, jkl]
</code></pre>

<p>I am new to programming. Trying to open Gmail using this code snippet. But problem is putExtra(Intent.EXTRA_EMAIL, strTo) does not give any result. putExtra(Intent.EXTRA_SUBJECT, strSubject) works fine. I tried to pass array also but result is same. Could someone please give suggestions for this email sender using kotlin.</p>
<pre><code>val etTo = findViewById<EditText>(R.id.etTo)
val etSubject = findViewById<EditText>(R.id.etSubject)
val emailBtn = findViewById<Button>(R.id.emailBtn)
emailBtn.setOnClickListener {

val strSubject = etSubject.text.toString()
val intent = Intent(Intent.ACTION_SENDTO).apply {
data = Uri.parse("mailto")
putExtra(Intent.EXTRA_EMAIL, strTo)

<p>I can use an unconstrained type paramter:</p>
<pre><code>interface State<V>
</code></pre>
<p>or I can use a constrained type parameter:</p>
<pre><code>interface State<V: Any>
</code></pre>
<p>This seems to be the same, because <a href="https://kotlinlang.org/docs/basic-types.html" rel="nofollow noreferrer">"In Kotlin, everything is an object [...]"</a>. But this may be deceptive. What consequences does it have, if I favor the second instead of the first?</p>

<p>In a SpringBoot Controller class, my APIs usually return a ResponseEntity with a body and a status code. But I can apparently dispense with the ResponseEntity by annotating my controller method with <code>@ResponseBody</code>, like this:</p>
<pre><code>@Controller
public class DemoController
{
@Autowired
StudentService studentService;
@GetMapping("/student")
@ResponseBody
Student getStudent(@RequestParam id) {
return studentService.getStudent(id);
}
}
</code></pre>
<p>If my service throws an exception, I can return a custom HTTP status by throwing a <code>ResponseStatusException</code>, but it's not clear how to specify the HTTP status for a valid response. How would I specify this? Or how does it decide what to use?</p>

<p>I thought my function result is returning two values that are stored in the variable <code>results</code> as a tuple, and that I can then access with <code>results[0], results[1]</code>.
But apparently I'm wrong.</p>
<pre><code>`i = 0
result = result(new_data[i][0], new_data[i][1])
print(result)
`
</code></pre>
<p>Returns my desired output
<code>('loss', 2)</code></p>
<p>This I tried and it returned the values I expected. But these values don't seem to get put into the function.</p>

<p>I am trying to overwrite specific rows and columns from one dataframe with a second dataframe rows and columns. I can't give the actual data but I will use a proxy here.</p>
<p>Here is an example and what I have tried:</p>
<pre><code>df1
UID B C D
0 X14 cat red One
1 X26 cat blue Two
2 X99 cat pink One
3 X54 cat pink One
df2
UID B C EX2
0 X14 dog blue coat
1 X88 rat green jacket
2 X99 bat red glasses
3 X29 bat red shoes
</code></pre>
<p>What I want to do here is overwrite column <code>B</code> and <code>C</code> in <code>df1</code> with the values in <code>df2</code> based upon <code>UID</code>. Therefore in this example <code>X88</code> and <code>X29</code> from <code>df2</code> would not appear in <code>df2</code>. Also column <code>D</code> would not be affected and <code>EX2</code> not</p>
<p>The outcome would looks as such:</p>
<pre><code>df1
UID B C D
0 X14 dog blue One
1 X26 cat blue Two
2 X99 bat red One
3 X54 cat pink One
</code></pre>
<p>I looked at this solution : <a href="https://stackoverflow.com/questions/58226481/pandas-merge-two-dataframe-and-overwrite-rows">Pandas merge two dataframe and overwrite rows</a>
However this appears to only update null values whereas I want an overwrite.</p>
<p>My attempt looked this like:</p>
<pre><code>df = df1.merge(df2.filter(['B', 'C']), on=['B', 'C'], how='left')
</code></pre>
<p>For my data this actually doesn't seem to overwrite anything. Please could someone explain why this would not work?</p>
<p>Thanks</p>

<p>I am trying to sort datas which are fetched from firebase realtime database according to the value of a child using MVVM architecture the daabase reference is created in a repository</p>
<p><strong>GroupNoticeRepository</strong></p>
<pre><code>class GroupNoticeRepository(private var groupSelected: String) {
val auth = Firebase.auth
val user = auth.currentUser!!.uid
private val scheduleReference: DatabaseReference =
FirebaseDatabase.getInstance().getReference("group-notice").child(groupSelected)
@Volatile
private var INSTANCE: GroupNoticeRepository? = null
fun getInstance(): GroupNoticeRepository {
return INSTANCE ?: synchronized(this) {
val instance = GroupNoticeRepository(groupSelected)
INSTANCE = instance
instance
}
}
fun loadSchedules(allSchedules: MutableLiveData<List<GroupNoticeData>>) {
scheduleReference.addValueEventListener(object : ValueEventListener {
override fun onDataChange(snapshot: DataSnapshot) {
try {
val scheduleList: List<GroupNoticeData> =
snapshot.children.map { dataSnapshot ->
dataSnapshot.getValue(GroupNoticeData::class.java)!!
}
allSchedules.postValue(scheduleList)
} catch (_: Exception) {
}
}
override fun onCancelled(error: DatabaseError) {
}
})
}
}
</code></pre>
<p><strong>GroupNoticeFragment</strong></p>
<pre><code>override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
recycler = binding.taskList
recycler.layoutManager = LinearLayoutManager(context)
recycler.setHasFixedSize(true)
adapter = GroupNoticeAdapter(_inflater)
recycler.adapter = adapter
viewModel = ViewModelProvider(this)[GroupNoticeViewModel::class.java]
viewModel.initialize(groupId)
viewModel.allSchedules.observe(viewLifecycleOwner) {
adapter!!.updateUserList(it)
}
}
</code></pre>
<p><strong>GroupNoticeViewModel</strong></p>
<pre><code>
class GroupNoticeViewModel : ViewModel() {
private lateinit var repository: GroupNoticeRepository
private val _allSchedules = MutableLiveData<List<GroupNoticeData>>()
val allSchedules: LiveData<List<GroupNoticeData>> = _allSchedules
fun initialize(groupSelected: String) {
repository = GroupNoticeRepository(groupSelected).getInstance()
repository.loadSchedules(_allSchedules)
}
}
</code></pre>
<p>`<a href="https://i.stack.imgur.com/d1tPF.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/d1tPF.jpg" alt="enter image description here" /></a></p>
<p>As you can see the current structure
group-notice
-groupId(groups)
-noticeId (notices)
- taskDate</p>
<p>Here under group notice there are some groups and in each group there are some notices(noticeId) .
Each notice has a task date . Now I am trying to sort the notices according to the taskdate meaning the taskDate which will is closer to todays date will view first in the recycler view. Or the notice with latest taskdate given will appear first in the recycler view .</p>

<p>if the user enters a char it should show the wrong input and continue asking for input until it reaches the range of 10 elements. how to solve this? output</p>
<pre><code>list = []
even = 0
for x in range(10):
number = int(input("Enter a number: "))
list.append(number)
for y in list:
if y % 2 == 0:

<p>I have a table with 8,000 rows of data and a small sample of it here:</p>
<pre><code>Customer ItemDescription Invoice PurchaseDate
1064 Produce 55514 22-01
1064 Snack 55514 22-01
1080 Drink 56511 23-01
1080 Snack 56511 23-01
1230 Drink 55551 26-03
1230 Snack 55551 26-03
1128 Meat 55003 04-03
1128 Snack 55003 04-03
1229 Drink 55100 06-03
1229 Snack 55100 06-03
1230 Meat 55102 07-03
1230 Snack 55102 07-03
</code></pre>
<p>I am trying to find the top 3 items that customers have bought along with "Snack".</p>
<p>So the printed result should look like this:</p>
<pre><code>0 Drink
1 Meat
2 Produce
</code></pre>
<p>I have tried df.groupby but it doesn't sort them based on what was purchased along with "snacks".</p>

<p>I have a CartController with the following function:</p>
<pre><code> public function getTotalCartPrice()
{
$totalCartPrice = 1;
return $totalCartPrice;
}
</code></pre>
<p>Cart.blade.php</p>
<pre><code><h3 class="cartTotal">Cart total: {{ Cart::getTotalCartPrice }} </h3>
</code></pre>
<p>Routes</p>
<pre><code>Route::resource('/cart', CartController::class);
</code></pre>
<p>Using this does not seem to display the total cart price and I get an error saying class "Cart" not found. I have attempted to change my route to this:</p>
<pre><code>Route::get('/cartPrice', [CartController::class, 'getTotalCartPrice'])->name('getTotalCartPrice');
</code></pre>
<p>and then inside my blade view:</p>
<pre><code><h3 class="cartTotal">Cart total: {{ route('getTotalCartPrice') }} </h3>
</code></pre>
<p>But I just get an output on the website:</p>
<pre><code>Cart total: http://localhost/cartPrice

<p>on my Project I have a banner on top of my site with 2 buttons. when I click the button profile I want it to change the css style of a div in another component.
this is my code for the banner:</p>
<pre><code>import Profile from "./Profile";
function Banner() {
const invis=false;
return (
<div className="banner">
<span className="bannerbtnsettings">
<button className="btnbannersettings">Settings</button>
</span>
<span className="bannerbtnprofile">
<button className="btnbannerprofile" onClick={Profile.changeStyle}>Profile</button>
</span>
</div>
);
}
export default Banner;
</code></pre>
<p>this is my code for the div in the other component:</p>
<pre><code>import "../index.css";
import React, { useState } from "react";
const Profile = () => {
const [style, setStyle] = useState("profile-hidden");
const changeStyle = () => {
console.log("you just clicked");
setStyle("profile-displayed");
};
return (
<div>
<div className={style}> hellllo</div>
</div>
);
};
export default Profile;
</code></pre>
<p>I can only find information about this with parent-child components.
They said I should use a usestate import but I can't seem to get it working. what's the proper way to do this?</p>

<p>Disabled users who cannot control a mouse use the keyboard to navigate the page. How do you allow them to select the various styles (like bold etc) in ckeditor5? These elements are NOT in the tabindex of the page by default.</p>
<p>Tabbing through a form, I expect to be able to interact with every interactable element on a page</p>

<p>So for my to-do list, im trying to show in my view the difference in number of days between the current date and the date that the task is suppose to be completed by. But i cant seem to do that because im using date_diff() function and it only accepts objects and not strings for the data types.</p>
<p>This is the error message</p>
<pre><code>date_diff(): Argument #1 ($baseObject) must be of type DateTimeInterface, string given
</code></pre>
<p>This is my controller</p>
<pre><code>public function saveItem(Request $request) {
$newTask = new task;
if ($request->task == null) {
abort(404);
}
$newTask->tasks = $request->task;
$newTask->is_complete = 0;
$newTask->task_date = date("Y-m-d");
if($request->day === "tomorrow") {
$date = date_create(date("Y-m-d"));
date_add($date, date_interval_create_from_date_string("1 day"));
$newTask->date_of_completion = date_format($date, "Y-m-d");
} elseif($request->day === "today") {
$newTask->date_of_completion = date("Y-m-d");
}
$newTask->save();
return redirect('/');
}
</code></pre>
<p>This is my view</p>
<pre><code><p class="flex items-center px-4 py-1 rounded-lg text-[#555]">{{ date_diff(date("Y-m-d"), date_create($task->date_of_completion)) }}</p>
</code></pre>
<p>If i can find out how to change or use something else to get the current date as an object so that it can be used in my date_diff(), it will really help but if you have a better solution that is much easier, im open it to it as well.</p>

<p>our electricity provider think it could be very fun to make difficult to read csv files they provide.</p>
<p>This is precise electric consumption, every 30 min but in the SAME column you have hours, and date, example :</p>
<p>[EDIT : here the raw version of the csv file, my bad]</p>

<p>I'm practicing format fuction and when I use this code with \t in it, the first 9 output did not have any big space
`</p>
<pre><code>import random
lst = [random.randint(1,100) for i in range(51)]
for index, val in enumerate(lst):
print(f'{index=}\t{val=}')
</code></pre>
<p>`</p>
<p>It works with \n but not \t, I don't know why. Can anyone explain it?</p>

<p>i am a web developer (php, js, css and ...).
i order a python script for remove image background. it worked in cmd very well but when running it from php script, it dosnt work.
i look at the script for find problem and i realized that the script stops at this line:</p>
<pre><code>net.load_state_dict(self.torch.load(os.path.join("../library/removeBG/models/", name, name + '.pth'), map_location="cpu"))
</code></pre>
<p>I guess the problem with the script is that it can't find the file, and probably the problem is caused by the path that os.path points to.
Is it possible to print the path that os .path points to?
If not, do you have a solution to this problem?</p>

<p>Hi I am still new to the rxjs of Angular.
I am building an Ionic app using Angular Fire.
I'm currently facing some problems here, I'm using Firebase as my backend, and I would have to query through different collections to fetch my data. For example, the first subscription only fetch user course enroll data like courseId, progress..., the second subscription would fetch the course details, and the third will fetch lecturer details. Can anyone give some suggestion on how to avoid using nested subscription because many people said it is not recommended to do so.
I would be very appreciated if you can provide some detailed explainations because I really only know the basics of rxjs.</p>
<p>I have tried concatMap but it shows firebase error(<a href="https://i.stack.imgur.com/6SOS0.png" rel="nofollow noreferrer">https://i.stack.imgur.com/6SOS0.png</a>)]</p>
<p><img src="https://i.stack.imgur.com/jgMwV.png" alt="" /></p>
<pre><code>collectionData(queryRef)
.pipe(
concatMap((res: any) => this.getCourse(res.courseId))
//concatMap((result2: any) => this.getLecturer(result2.lecturerId))
)
.subscribe((res) => {
console.log(res);
});
</code></pre>
<p>But actually I also not sure did I did it right because I really cannot understand how concatMap works.</p>

<p>I have a struct defined like the following (other fields removed for brevity):</p>
<pre><code>use chrono::{
DateTime,
Utc
};
use serde::{
Deserialize,
Serialize
};
#[derive(
Clone, Debug, PartialEq, Eq, Serialize, Deserialize
)]
pub struct Test {
#[serde(skip_serializing_if = "Option::is_none")]
#[serde(with = "bson::serde_helpers::chrono_datetime_as_bson_datetime")]
pub time_period: Option<Vec<DateTime<Utc>>>
}
</code></pre>
<p>And I'm using the following dependencies:</p>
<pre><code>bson = { version = "^2.4", default-features = false, features = [ "chrono-0_4" ] }
chrono = "^0.4"
serde = { version = "^1.0", default-features = false, features = [ "derive" ] }
</code></pre>
<p>But <code>serde</code> derivations throw error, because there is type mismatch. It expects a <code>DateTime</code> object, but we have an optional vector here. Any ideas how to serialize optional vector of <code>DateTime</code> objects?</p>

<p>I have a table that shows the date and time whenever an issuer has called the service. I want to write a query to show in a specific day the requests of an specific issuer has not covered the 24 hours. I will be appreciated if someone can guide me. I am beginner at SQL.
<img src="https://i.stack.imgur.com/JkLsJ.png" alt="mht_issuer_revoked_call" /></p>
<p>i tried to partition by issuerid and order by startdate and use the lag to compare startdate and enddate with previous record and add a new start and end date but i think i cant get the answer this way.</p>
<pre><code>select r.*,
case
when r.startdate > lag(r.enddate) over(partition by r.issuerid order by r.startdate) then r.startdate
else min(r.startdate) over(partition by r.issuerid order by r.startdate)
end startdate_new,
case
when lag(r.enddate) over(partition by r.issuerid order by r.startdate) is null then r.enddate
when r.enddate <= lag(r.enddate) over(partition by r.issuerid order by r.startdate) then lag(r.enddate) over(partition by r.issuerid order by r.startdate)
when r.enddate > lag(r.enddate) over(partition by r.issuerid order by r.startdate) then r.enddate
end enddate_new

<p>I have two SVG icons, and all I want to do is apply a background, add some padding, and make the <strong>padding</strong> appear round (border-radius). When adding the padding all is fine and appears as expected, it's only when trying to make it round.</p>
<p>No matter what the amount of padding is, the SVG's are cut off.</p>
<p>SVG with <code>10px padding</code> and <code>50% border-radius</code>:</p>
<p><a href="https://i.stack.imgur.com/WsglA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WsglA.png" alt="enter image description here" /></a></p>
<p>For reference, this is what the SVG normally looks like:</p>
<p><a href="https://i.stack.imgur.com/831mz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/831mz.png" alt="enter image description here" /></a></p>
<p>As I explained above, I tried many different padding sizes, but all result in a part of the SVG being cutoff. I've searched on the topic, but the only things I could find were:</p>
<p><a href="https://stackoverflow.com/questions/9409632/border-radius-and-padding-not-playing-nice">Link 1</a> - It was about another topic not related to mine.</p>
<p><a href="https://developer.mozilla.org/en-US/docs/Web/CSS/border-block-start" rel="nofollow noreferrer">Link 2</a> - I tried <code>border-block-start</code>, but unfortunately nothing happened.</p>
<p>Can anyone help me?</p>

<p>My expo application works normally on Expo go, even using the command bellow it still works.</p>
<blockquote>
<p>npx expo start --no-dev --minify</p>
</blockquote>
<p>But when building with different methods it don't work at all, with different crashes.</p>
<blockquote>
<p>eas build -p android --profile preview</p>
</blockquote>
<p>It generates the APK, when i drag to the emulator (android 11) it gets the "successful install", so I open and the splash screen shows, after that it crashes and the app disappear from the device. Looks like it was automatically uninstalled, because I can't find it anywhere in the files.</p>
<blockquote>
<p>expo build:android -t apk</p>
</blockquote>
<p>With the deprecated method above i still get a "successful install", but it never gets to the splash screen, just get a white screen and it never crashes or disappear from device.</p>
<p>I tried on multiple devices and android versions and i have the same problem with each build in all of them. So i guess the problem is the build. I couldn't find anyone else with the solution or a hint for it.</p>
<p>I tried uninstalling multiple npm packages to see if was the problem with no successes.</p>
<p>Its my first time working with React Native and Expo, so I can be missing something.</p>

<p>TrackPoint tp
Type: TrackPoint</p>
<p>The argument type 'TrackPoint
(where TrackPoint is defined in ...lib\trackpoint.dart)'
can't be assigned to
the parameter type 'TrackPoint (where TrackPoint is defined in ...lib\trackPoint.dart)'.dart
<strong>(argument_type_not_assignable)</strong>
trackpoint.dart(8, 7): TrackPoint is defined in ...lib\trackpoint.dart
trackPoint.dart(8, 7): TrackPoint is defined in ...lib\trackPoint.dart</p>
<p>Here is where the error is:</p>
<pre><code>import 'trackpoint.dart' show TrackPoint;
class TrackingStatus {
// ...
static void _triggerEvent(TrackPoint tp) {
// ...
TrackingStatusChangedEvent.trigger(tp); // <-- error on tp, see above
}
</code></pre>
<p>Here is what causes the error:</p>
<pre><code>class TrackingStatusChangedEvent {
static void trigger(TrackPoint tp) { // <-- causes error
// ...
}
static void trigger(tp) { // <-- works but tp should not be dynamic
// ...
}
</code></pre>
<p>Here is where TrackPoint comes from:</p>
<pre><code>
class TrackPoint {
static final List<TrackPoint> _trackPoints = [];
void _addTrackPoint() {
_trackPoints.add(this);
</code></pre>
<p>argument_type_not_assignable is not reasonable for me. Especially because the error message points to the same class in the same file as if they are something different</p>

<p>I read <a href="https://tkdodo.eu/blog/react-query-as-a-state-manager" rel="nofollow noreferrer">an article on using react-query as a state manager</a> and I am now trying to replace a context in my app with react-query (version 4).</p>
<p>Previously, I created a context with <code>useContext()</code> that stored a <strong>user account</strong> object for the logged-in user. I used react-query to fetch this data, and then <code>useReducer()</code> to modify the account object. However, I realized this is a mess and the relevant data is in react-query anyway, so I should get rid of the context and reducer and just use react-query directly (I am generating the user account object in the query that I make with react-query).</p>
<p>I generate the user account object in a custom hook:</p>
<pre><code>function useUser(): UseQueryResult<User, Error> {
const query = getInitialUserUrl;
const platform = usePlatformContext();
return useQuery<User, Error>(
queryKeyUseUser,
async () => {
const data = await fetchAuth(query);
if (didQueryReturnData(data)) {
return new User(platform, data[0]);
}
return new User(platform);
},
{
refetchOnReconnect: 'always',
refetchInterval: false,
},
);
}
export default useUser;
</code></pre>
<p>Now I have a mutation where I verify the user's email address (old way using context):</p>
<pre><code>const useMutationVerifyEmail = (): UseMutationResult<RpcResponseEmailVerify, Error, FormEmailVerifyInput> => {
const { userObject } = useUserContext();
return useMutation(
(data: FormEmailVerifyInput) => verifyEmail(userObject.id, data.validation_code),
},
);
};
</code></pre>
<p>I tried to replace the call to context with a direct call to <code>useUser()</code>:</p>
<pre><code>const useMutationVerifyEmail = (): UseMutationResult<RpcResponseEmailVerify, Error, FormEmailVerifyInput> => {
const { data: userObject } = useUser();
return useMutation(
(data: FormEmailVerifyInput) => verifyEmail(userObject.id, data.validation_code),
},
);
};
</code></pre>
<p>However, TypeScript complains that <code>Object is possibly 'undefined'</code> for <code>userObject</code>. I'm not sure why, because as far as I understand, <code>useUser()</code> always returns a <code>User</code> object.</p>
<p>How can I update my custom hook to return a <code>User</code> object so that I can use it instead of context?</p>
<p><strong>UPDATE</strong></p>
<p>I can wrap my <code>useUser()</code> hook in another hook:</p>
<pre><code>function useUserObject() {
const { data: userObject } = useUser();
if (userObject instanceof User) {
return userObject;
}
throw new Error('Failed to get account info!');
}
</code></pre>
<p>And then I can do <code>const userObject = useUserObject()</code> to get the user account object... but is this really the optimal way? Do I need to create a custom hook for a custom hook just to use my user objects like I do with <code>useContext()?</code></p>

<p>I want to display the data of the authenticated user and also produce a status code and a status message when the user is not authenticated. I am using Laravel API and Sanctum and this is what I have tried:</p>
<pre><code>public function me(Request $request){
$user = $request->user();
if($user)
{
return response()->json([
'status'=>200,
'user'=>$user
]);
} else {
return response()->json([
'status'=>401,
'message'=>'No access'
]);
}
}
</code></pre>
<p>Problem is, it displays the status 200 when authenticated and does not display the status 401 code when not. It only displays the default Sanctum</p>
<pre><code>{
"message": "Unauthenticated."
}
</code></pre>
<p>There is also a bearer token involved in the authentication.
Kindly help</p>

<p>I want to make a set of floating point numbers, but with a twist:</p>
<p>When testing if some float x is a member of the set s, I want the test to return true if s contains some float f such that</p>
<pre><code>abs(x - f) < tol
</code></pre>
<p>In other words, if the set contains a number that is close to x, return true. Otherwise return false.</p>
<p>One way I thought of doing this is to store numbers in a heap rather than a hash set, and use an approximate equality rule to decide whether the heap contains a close number.</p>
<p>However, that would take log(N) time, which is not bad, but it would be nice to get O(1) if such an algorithm exists.</p>
<p>Does anyone have any ideas how this might be possible?</p>

<p>Could you please help me figure out why is this not working i.e. refering to the comment in the code <code>//I need to do this but I can't. I thought this the goal!</code>? I have no idea why this is not working, it's inspired by examples I have seen online.</p>
<pre><code>#include <variant>
#include <iostream>
template<typename... args>
class Visitor //: public boost_base_visitor<double>...
{
public:
virtual ~Visitor() = default;
virtual double visit(typename std::variant<args...> visitable)
{
auto op = [this](typename std::variant<args...> visitable) -> double { return this->apply(visitable); };
return std::visit(std::ref(op), visitable);
}
virtual double apply(typename std::variant<args...> visitable) = 0;
Visitor() = default;
};
class SubVisitor : public Visitor<std::string, double>
{
public:
virtual ~SubVisitor() = default;
SubVisitor() : Visitor<std::string, double>() {};
virtual double apply(std::variant<std::string, double> visitable) override
{
//return process(visitable); //I need to do this but I can't. I thought this the goal!
return process(std::get<std::string>(visitable)); //I DON'T KNOW IF THIS IS REALLY A STRING??
};
virtual double process(std::string visitable)
{
std::cout << "STRING HANDLED" << std::endl;
return 0.0;
}
virtual double process(double visitable)
{
std::cout << "DOUBLE HANDLED" << std::endl;
return 1.0;
}
};
int main(int argc, char* argv[])
{
SubVisitor v;
v.apply("dd");
//v.apply(1.0); //This will fail as we only handle string?? What is the purpose of variant then?
return 1;
}
</code></pre>
<p>I am getting error when uncommenting the <code>process</code> function above:</p>
<blockquote>

<p>I'm making a simple to-do app with add and delete functionality and I want to implement an undo-delete option.</p>
<p>So far, I've tried using context but I have a problem with context state logic: undo function uses not-yet updated state values, which leads to errors.</p>
<p>The problem is better documented in the demo:</p>

<p>you see I'm getting the error file already exists, so what I want it to add a number to the QR code every time someone saves it. So it doesn't throw the error, you see python and shutils just gets confused when saving a file with the same name 2 times. If you don't really get what I'm saying then just tell me to make some edits, ill make it simpler.</p>

<p>I try to fetch 4 categories from my DB.</p>
<p>I get the category, everything is ok but when I submit my form, I get this data :</p>
<pre><code>[object%20Object],[object%20Object],[object%20Object],[object%20Object]
</code></pre>
<p>Here the code :</p>
<pre><code>//State
const [cates, setCates] = useState([]);
// Fetch 4 categories
useEffect(() => {
const getCates = async () => {
const res = await axios.get("http://localhost:8080/api/categories");
setCates(res.data);
};
getCates();
}, [])
//Map the categories from the State : cates
const Categorie = cates.map((c) => (
<option value={c.name}>{c.name}</option>
))
</code></pre>
<p>My component :</p>
<pre><code><Select>
<option value="" hidden>Choisissez une catégorie</option>
{Categorie}
</Select>
</code></pre>
<p>The console.log(Categorie) return an Array of object :</p>
<pre><code>(4) [{…}, {…}, {…}, {…}]
0
:
{$$typeof: Symbol(react.element), type: 'option', key: null, ref: null, props: {…}, …}
1
:
{$$typeof: Symbol(react.element), type: 'option', key: null, ref: null, props: {…}, …}
2
:
{$$typeof: Symbol(react.element), type: 'option', key: null, ref: null, props: {…}, …}
3
:
{$$typeof: Symbol(react.element), type: 'option', key: null, ref: null, props: {…}, …}
length
:
4
[[Prototype]]
:
Array(0)
</code></pre>
<p>And the console.log(cates[0].name) give me the result I'm looking for.</p>
<p>But even when I try to put manually the categories like that : cates[0].name, cates[1].names etc... I get a blank page when I save my code and reload the page.</p>
<p>I just want to get my the categorie selected.</p>

<p>Here's my sample code:</p>
<pre><code>public class MyList<T extends Number> {
private List<T> items;
public void func() {
items.add(Integer.valueOf(1));
}
}
</code></pre>
<p>I think I should be able to add integer to items, but compilation fails:</p>
<pre><code>Required type: T
Provided: Integer
</code></pre>
<p>Anyone knows what's wrong here?</p>

<p>I'm currently working on a website and I it's putting line breaks where I don't believe it should.</p>
<p>For example if I'd do:</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-html lang-html prettyprint-override"><code><p>a</p><p>b</p></code></pre>
</div>
</div>
</p>
<p>it'd put a line break between them. Has it always been this way?</p>

<p>I want to generate a random binary matrix, so I'm using <code> W=np.random.binomial(1, p, (n,n))</code>.
It works fine, but I want a constraint that no row is just of 0s.</p>
<p>I create the following function:</p>
<pre class="lang-py prettyprint-override"><code>def random_matrix(p,n):
m=0
while m==0:
W = np.random.binomial(1, p, (n,n))
m=min(W.sum(axis=1))
return W
</code></pre>
<p>It also works fine, but it seems to me too inefficient. Is there a faster way to create this constraint?</p>

<pre><code>user_input = int(input('Enter input: '))
if type(user_input) == "<class 'int'>":
print('This is a integer.')
</code></pre>
<p>The code above outputs nothing to the console. I am just confused because it is very simple and looks like it should work.</p>
<p>I've tried removing the int() in the input line which output nothing, I understand this because user_input turns into a string but I do not understand why it outputs nothing when user_input is defined as an integer.</p>

<p>I try to make a simple file upload server. I wonder if it stores the uploaded file in a ram or hard disk since the container itself run as a virtual-machine in ram so it should not be able to have access to the disk right? unless I specify the bind-mounted volume option. So if the user upload a lot of files to the server at some points it's going to crash since it doesn't have ram space to store the files.</p>

<p>Im just curious why the linethrough worked on everything even the textbox placeholders but not with the text inside all the buttons, with css or not.
``</p>
<pre><code>function strike(){
document.getElementById("root").style.textDecoration= "line-through";
}
function unstrike(){
document.getElementById("root").style.textDecoration= null;
}
function App() {
return (
<div className="container">
<Form state={userIsRegistered} />
<button onClick={strike}>strike</button>
<button onClick={unstrike}>unstrike</button>
</div>
);
}
</code></pre>
<p>``</p>
<p>Even if i targeted the root. What should I do to include it when i click on the strike button?</p>

<p>This will raise an <code>Error: Hydration failed because the initial UI does not match what was rendered on the server.</code> error:</p>
<pre class="lang-js prettyprint-override"><code>const [selectedOrganizationShortId, setSelectedOrganizationShortId] =
useLocalStorage<string>('teamId', undefined)

<p>This will not:</p>

useState<string>(undefined)
const [selectedProgramId, saveSelectedProgramId] = useState<
string | undefined
>(undefined)

<p>though both does the same. I would use <code>useLocalStorage</code> as it is handy convenience solution, but seems it is not compatible with Next.js.</p>
<p><code>useLocalStorage</code> is used from here: <a href="https://usehooks-ts.com/react-hook/use-local-storage" rel="nofollow noreferrer">https://usehooks-ts.com/react-hook/use-local-storage</a></p>

<p>I have a hitbox with a script called "accept", I then have 2 prefabs that have a public bool of "isPoor". One of the prefabs = true, the other = false.</p>
<p>When the prefabs with isPoor = true goes into the "accept" hitbox I want the game to fail, and when isPoor = false goes into "accept" hitbox I want the player to win.</p>
<p>The problem with the code I have is that it only ever fails the game, even when an NPC with isPoor = false goes into the "accept" hitbox.</p>
<p>This is the code for the accept hitbox.</p>

isPoor = other.gameObject.GetComponent<Poor>().isPoor;
if (isPoor = true)
{
gameManager.GameOver();
}
if (isPoor = false)
{
gameManager.GameWon();
}
Destroy(other.gameObject);
Spawner.GetComponent<Spawner>().Spawn();
}
}
</code></pre>
<p>It's my first time using Unity so I'm a bit stumped. But it seems that the script just treats both prefabs as if they had isPoor = true.</p>

<p>I don't understand what the difference between</p>
<pre class="lang-c prettyprint-override"><code>int main(int argc, char* argv[]){;}
</code></pre>
<p>and</p>
<pre class="lang-c prettyprint-override"><code>int main(int argc, const char* argv[]){;}
</code></pre>
<p>is.</p>
<p>I'm aware of the difference between a <code>char*[]</code> and <code>const char*[]</code> but I wonder why one would like to use the latter.</p>
<p>Are there use cases where one would want to change command line arguments? What's the best practice about adding <code>const</code>?</p>

<p>I am trying to remove unnecessary patterns like "\n\n", "\r\r", "\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n"
While parsing, I want to remove all the special patterns and want to have only text and numbers.</p>
<p>I have tried as below.</p>
<pre><code>with open (data, "r", encoding='utf-8') as myfile:
for line in myfile:
line.rstrip()
line = re.sub(r'\r\n', '', line)
with open("out.txt", "a", encoding='utf-8') as output:
output.write(line)
</code></pre>
<p>But even '\r\n' is not getting removed in output file. Thanks.</p>

<p>I am currently working on a program that should create a list out of your own inputs. It should list your inputs under each other but if I try to press the "Hinzufügen" button (Enter button), nothing happens and my inputs aren't listed. This is for a school project and I am stuck with this for some time.</p>
<p>I already tried to look if I made some spelling mistakes and I corrected them. I really don't know what makes my programme not working. I would appreciate any help.</p>

<p>I need to have an async consumer method to consume messages from RabbitMq. My problem is that the rabbitmq client for .net rely on an event handler.
I tried to implement a blocking system with a Semaphore, which is working with a low volume. When I'm getting more volume, some messages are lost.</p>
<p>Here is my implementation :</p>
<pre><code> private long _lock;
private string _message;
private object _tag;
private readonly SemaphoreSlim _signal;
public void Configure()
{
Interlocked.Exchange(ref _lock, 0);
var consumer = new EventingBasicConsumer(_channel);
consumer.Received += (sender, ea) =>
{
_message = Encoding.UTF8.GetString(ea.Body.ToArray());
_tag = ea.DeliveryTag;
Interlocked.Exchange(ref _lock, 1);
_signal.Release();
};
_channel.BasicConsume(queue: _rabbitConfig.Queue, autoAck: true, consumer: consumer);
}
public async Task<string> Consume(CancellationToken cancellationToken)
{
while (0 == Interlocked.Read(ref _lock))
{
await _signal.WaitAsync();
}
Interlocked.Exchange(ref _lock, 0);
return _message;
}
</code></pre>
<p>I alse tried using BufferBlock but some messages are still lost.
Is there any other way to implement a system keeping my Consume() method ?</p>
