In this tutorial, you'll learn about indefinite iteration using the Python while loop. You'll be able to construct basic and complex while loops, interrupt loop execution with break and continue, use the else clause with a while loop, and deal with infin
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合...

In Python, a basic while loop looks like this: while[a conditionisTrue]: [do something] The condition we provide to the while statement is the controlling expression, our loop will run until the controlling statement is no longer true. ...
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, ...
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...
Python 零基础新手入门 #06 While Loop (回圈)樂柠英格力仕啊噗啊噗编辑于 2022年11月22日 21:41 终于把如果小明和小华同时都输入正确答案时应该做的逻辑写出来了[妙啊]虽然语法结构不太精简,但是新手的尝试很兴奋。 我觉得if可以再简化一下,从系统理论来讲,这是可以实现的。只是我很好奇,if语句的子句不能...
While loops are primarily used in Python when the number of iterations can’t be determined at the time of writing the code. Keep reading to find out how the Python while loop works. Tip Teach yourself how to program in Python with our Python tutorial. What is the while loop in ...
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。
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。
