问题 I am trying to do a speed camera program by using a while loop to add up time. I want the user to be able to input "Enter" to stop the while loop with out the while loop pausing and waiting for the user input something, so the while loop works as a clock. import time timeTaken=float(0) while True: i = input #this is where the user either choses to input "Enter" #or to let the loop continue if not i: break time.sleep(0.01) timeTaken=timeTaken+0.01 print(timeTaken) I need a line of code which

问题 I am writing a simple journal program with python. I used sys.stdin.readlines() so the user could press enter to start a new paragraph and not have to program quit. The problem is that when it writes the input to the text file it skips the first paragraph they enter. so anythying that they write before starting a new line isn't written to the file. #!/usr/bin/python import sys def main(): #begin stand alone program print "\nPlease tell me about your day.\n"; userEntry = raw_input() #assigns

问题 I'm taking a look at Rust and decided to build a small program that takes a user's input and prints it, but also want to do some math stuff with it for practice. Currently, this is how I am taking user input: let mut number = String::new(); let input = io::stdin().read_line(&mut number) .ok() .expect("Failed to read line"); println!("You entered {}", number); However, although I do get the correct input this way, Cargo gives me the following warning: src/main.rs:10:9: 10:14 warning: unused

问题 I'm trying to make a function that checks for an integer and will keep looping until the user correctly enters an integer of 17 or higher. However, if I put in wrong input, like 'K', or '&', it will get stuck in an infinite loop. public static int getAge(Scanner scanner) { int age; boolean repeat = true; while (repeat) { try { System.out.println("Enter the soldier's age: "); age = scanner.nextInt(); repeat = false; } catch(InputMismatchException exception) { System.out.println("ERROR: You

问题 This question already has answers here : Limiting TextField inputs (2 answers) Closed 6 years ago . I figured this would be a simple search on the web but I can't figure this out. Here is what I'm working with so far. Ignore the eventHandler, I know its empty. I want to limit the charField JTextField so that the user can only type one character. I figured this would be easy because of all the apps that limit the amount of numbers you can type when entering State or Zipcode. To be clear, I'm

问题 Stuck with a strange situation where neither react input nor material-ui TextField works when put inside a material-ui TreeView. The same work when pulled out of the TreeView. Sharing the code below CustomTreeView.js import React, { useState } from "react"; import Grid from "@material-ui/core/Grid"; import Paper from "@material-ui/core/Paper"; import TreeView from "@material-ui/lab/TreeView"; import ExpandMoreIcon from "@material-ui/icons/ExpandMore"; import ChevronRightIcon from "@material

问题 I want to re-generate user's input values onto textarea with specific format. I've created input and 'select' with various 'options' inside as well as 'button' that triggers the function. Can someone please tell me what I'm doing wrong here..? <SCRIPT> function myFunction() { var finaL = document.getElementById("textArea").value; var spacE = " | "; var a = document.getElementById("input1").value; var b = document.getElementById("input2").value; var c = document.getElementById("selecT").value;

问题 I am using input type text box with pre populated values and when I click on the input box the position of the cursor is moving to the start which is not happening in other browsers(only IE11 is the issue present). It's very annoying and spent hours debugging . In fact debugging in IE is very pain. Please note I do not want to manipulate the DOM and we are not suppose to use Jquery anymore in our application. I am using react Js as UI framework. It would be great if someone give some hint on

问题 I'm learning Java coming from other programming languages (Js, C and others..) I'm wondering if under any circumstances the Scanner.next() method could return (without throwing) an invalid string or less than one character (ie. null or empty string "" ). I'm used to double-check user input for any possible unexpected/invalid value, but I wanted to know if testing for null and myString.length() < 1 is always unnecessary or could be useful/needed. I'm asking in particular when reading from the
