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 ...
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...
while expression: statement(s) 1. 2. while loop - 流程图 在这里,while循环的关键点是循环可能永远不会运行。当测试条件并且输出为false时,将跳过循环体,并执行while循环后的第一个语句。 while loop - 示例 #!/usr/bin/python count=0 while (count < 9): print 'The count is:', count count=coun...
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 the loop and the first time when the expression evaluates to False, the loop stops without executing any remaining statement(s). ...
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 »...
Overview of While Loop in Python The While Loop is a type of entry-level control statement that can be used for executing a set of program code repeatedly based on a condition set for the loop. This conditional statement starts with the ‘While’ keyword and a condition next to it, follow...
A while loop in Python repeats as long as a condition is true. Here is the basic syntax with an example: while condition: statement(s) For example: counter = 0 while counter < 5: print(counter) counter = counter + 1 This prints the numbers 0 to 4. The flowchart below shows each st...

A while loop has three important parts:The keyword while, followed by a space. The condition you test. If the condition is true, the code inside the while loop runs. The code you want to run for each iteration, indented with nested whitespace. For example: Python Copy while <condition>...
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在一起,但无法同时运行这两...
