while-loop

问题 I have a piece of code with while loop which I would like to stop by setTimeout(). But it seems like a endless loop, which never triggers setTimeout(). If I remove while loop, timeout triggers correctly. What is wrong please? $(document).ready(function() { var i = 0, s = false; setTimeout( function() { s = true; console.log( "Timeuot!!!" ); console.log( "s value is " + s ); }, 1000 ); while( s === false ) { console.log( "this is while and s is " + s ); i++; } console.log( "iterations: " + i )

问题 I'm a new programmer trying to practice by making a game. I want the player to be able to set their own name, as well as answer yes or no as to whether that name is correct. I did this by using a while loop. However, since the name is initialized inside the loop, I cannot use it outside. I was wondering if there was anyway to do so. My code is probably very basic and messy. I apologize for that. Scanner input = new Scanner(System.in); String name; int nameRight = 0; while (nameRight == 0) {

问题 I am trying to run a Promise within a while loop. The code after the promise (in the .then) will eventually break the while loop. However, the promise never runs. The while loop just keeps running infinitely without triggering the promise. Why is this? Is it impossible to use a promise in a while loop? A simplified version of code is below while(relevantRefundRequests.length >= waitList[0].quantity){ stripe.paymentIntents.create({ }) .then(data => { ***code that will break while loop }) } 回答1

问题 I am making a Stochastic Gradient Descent Classifier (SGDClassifier) using scikit- learn. While Fitting my training data (of shape (60000,784)), I am getting memory error. How to fix it? I have already tried switching from 32 bit to 64 bit IDE. And reducing the training data will decrease the performance (that is basically not the option). Code: (Python 3.7) # Classification Problem # Date: 1st September 2019 # Author: Pranay Saha import pandas as pd x_train= pd.read_csv('mnist_train.csv') y

问题 I am using the Star Wars API https://swapi.co/ I need to pull in starships information, the results for starships span 4 pages, however a get call returns only 10 results per page. How can I iterate over multiple pages and get the info that I need? I have used the fetch api to GET the first page of starships and then added this array of 10 to my totalResults array, and then created a While loop to check to see if 'next !== null' (next is the next page property in the data, if we were viewing
