Workflow+Start+Initialize conditions+Check multiple conditions+Execute loop body+Update conditions+End loop when conditions are false 接下来看一下实现这个流程的步骤: 每一步的具体实现 现在,让我们逐步实现上面的流程。 1. 开始 我们从最基本的Python程序开始,首先需要确保您可以运行Python环境。 # 导入所需的...
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...
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 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...

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。
Python Syntax whileTrue:ifcondition_1:break...ifcondition_2:break...ifcondition_n:break This syntax works well when you have multiple reasons to end the loop. It’s often cleaner to break out from several different locations rather than try to specify all the termination conditions in the lo...
这是一个非常简单的掷骰子程序,它会不断掷两个骰子,直到得到双六。所以我的 while 语句结构如下: {代码...} 出于某种原因,程序在 DieOne 得到 6 后立即结束。 DieTwo 根本不考虑。 但是,如果我在 while 语句...
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. ...
