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结...
Here, the condition of the while loop is alwaysTrue. However, if the user entersend, the loop termiantes because of thebreakstatement. Pythonwhileloop with anelseclause In Python, awhileloop can have an optionalelseclause - that is executed once the loop condition isFalse. For example, coun...

Python 中的 while 语句可以基于某个条件成立的情况下重复执行一个代码块。它的语法如下：whilecondition:...
The code in the body of a while loop is executed repeatedly. This is called iteration. while循环体中的代码被重复执行。这叫做迭代。 The infinite loop is a special kind of while loop; it never stops running. Its condition always remains True. ...
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。
whilecondition:# while 是循环的关键字。# 循环体 # condition是循环的条件,当条件为真时,循环体会一直执行。 [2]使用 count =0whilecount <5:print("Current count:", count) count +=1print("Loop finished!")# Current count: 0# Current count: 1# Current count: 2# Current count: 3# Current ...
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...
