Pythonwhileloop withbreakstatement We can use abreak statementinside awhileloop to terminate the loop immediately without checking the test condition. For example, while True: user_input = input('Enter your name: ') # terminate the loop when user enters end if user_input == 'end': print(f...
The condition is checked every time at the beginning of the loop and the first time when the expression evaluates to False, the loop stops without executing any remaining statement(s). The following example prints the digits 0 to 4 as we set the condition x < 5. x = 0; while (x < ...
ExampleGet your own Python Server Print i as long as i is less than 6: i =1 whilei <6: print(i) i +=1 Try it Yourself » Note:remember to increment i, or else the loop will continue forever. Thewhileloop requires relevant variables to be ready, in this example we need to def...
After that, we test what the user entered to see if it matches the ship’s location. If it does, Python says “It’s a hit!” and ends the loop. Otherwise, we just put an X on the grid so the user knows he already tried that place. Line 40 takes away one torpedo. Lines 42 ...
For example, say that you want to implement a number-guessing game. You can do this with a while loop: Python guess.py from random import randint LOW, HIGH = 1, 10 secret_number = randint(LOW, HIGH) clue = "" # Game loop while True: guess = input(f"Guess a number between {LO...
解决While loop问题 - Python 当我们在使用while循环时,需要确保循环的终止条件最终会被满足,否则循环将会无限执行下去。通常情况下,我们可以在循环内部修改循环控制变量,使得终止条件得以满足。 1、问题背景 一位开发者在使用 Python 开发一个基于文本的游戏时,遇到了 while 循环的问题。他将游戏代码和音频处理代码...
An example of an infinite loop: while 1==1: print("In the loop") This program would indefinitely print "In the loop". You can stop the program's execution by using the Ctrl-C shortcut or by closing the program. 无限循环是一种特殊的while循环;它从不停止运行。它的条件总是正确的。

如果你對for迴圈或if陳述句不熟悉,可以閱讀〈Python for 迴圈(loop)的基本認識與7種操作〉、〈Python if 陳述句的基礎與3種操作〉。 Python while 迴圈句基本認識 先來看一個簡單的while迴圈。 例子是這樣的,你要用Python印出1到100。你可以設定一個變數i,並在while後頭陳述符合需求的條件,條件是只要i小於...
Example 1: while Loop using System; namespace Loop { class WhileLoop { public static void Main(string[] args) { int i=1; while (i<=5) { Console.WriteLine("C# For Loop: Iteration {0}", i); i++; } } } } When we run the program, the output will be: C# For Loop: Iterati...
