Pythonwhileloop withbreakstatement We can use abreak statementinside awhileloop to terminate the loop immediately without checking the test condition. For example, whileTrue: user_input =input('Enter your name: ')# terminate the loop when user enters endifuser_input =='end':print(f'The loop ...
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...
while迴圈是你編寫程式語言的得力助手,有了while迴圈你可以讓Python依照你設定的條件執行指定的事。 對初學者而言,while迴圈可能不是很好懂的語法,透過實作練習觀念才會慢慢融會貫通,如果想透由小型專題練習,熟悉Python while 迴圈,推薦使用《Python 自動化的樂趣(第2版)》,在學習如何設計猜數字、剪刀石頭布的遊戲...
The while Loop With thewhileloop we can execute a set of statements as long as a condition is true. 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 »...
Python While 循环语句 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。
The basic loop structure in Python is while loop. Here is the syntax.Syntax:while (expression) : statement_1 statement_2 ...The while loop runs as long as the expression (condition) evaluates to True and execute the program block. The condition is checked every time at the beginning of...

If you come from languages likeC,C++,Java, orJavaScript, then you may be wondering where Python’s do-while loop is. The bad news is that Python doesn’t have one. The good news is that you can emulate it using awhileloop with abreakstatement. ...
while True意思是要一直进行loop(死循环)，也就是无限循环。死循环就是一个无法结束的循环。出现死循环是因为没有设置好结束条件，循环的结束条件很重要，要充分考虑各种边界情况。在合作式多任务的操作系统中，死循环会使系统没有反应，若是先占式多任务的系统中，死循环会用掉所有可用的处理器时间，不过可以由使用...
