Python Syntax while condition: In this syntax, condition is an expression that the loop evaluates for its truth value. If the condition is true, then the loop body runs. Otherwise, the loop terminates. Note that the loop body can consist of one or more statements that must be indented...
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结合在一起,但无法同时运行这两个循环。游戏代码使用 while True 循环不断等待玩家输入命令,而音频处理代码也使用 while True 循环不断处理音频消息。当玩家输入命令时,音频会停止播放,直到命令执...

A while loop in Python repeatedly executes a target statement as long as a given condition is true. The syntax of a while loop is straightforward: while condition: # execute these statements Powered By Here's a basic example: number = 0 while number < 5: print(f"Number is {number}")...

Python3 实例 我们将使用 Python 的while循环来打印从 1 到 10 的数字。while循环会一直执行,直到给定的条件不再满足为止。 实例 i=1 whilei<=10: print(i) i +=1 代码解析: i = 1:初始化变量i,并将其值设置为 1。 while i <= 10::这是一个while循环,只要i的值小于或等于 10,循环就会继续执行...
while陳述句(statement)所建立的迴圈不像for迴圈,需要在一定的範圍內迭代;也不像if陳述句,只存在執行一次或不執行的狀況。只要陳述的條件為真True,while迴圈就會持續到天荒地老,或者電腦當掉。 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...
While Loop In Python A while statement iterates a block of code till the controlling expression evaluates to True. While loop favors indefinite iteration, which means we don't specify how many times the loop will run in advance. In Python, a basic while loop looks like this: ...
The syntax of python’s while loop is: while condition: #The loop body The‘condition’will be the criteria based on which the loop body will be executed. Till the condition holds true, the loop body is executed. As soon as it becomes false, python will stop executing the loop body. ...
