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,直到命令执行完毕后才会继续...

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...
Python 编程中 while 语句用于循环执行程序,即在某条件下,循环执行某段程序,以处理需要重复处理的相同任务。其基本形式为: while判断条件(condition):执行语句(statements)…… 执行语句可以是单个语句或语句块。判断条件可以是任何表达式,任何非零、或非空(null)的值均为true。
