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...
While循环不中断(Python) python loops while-loop 我以前使用过while循环和类似的循环,但是这个循环根本达不到中断的条件。这个游戏是关于在盒子里找到隐藏的东西。我放了一些在实际游戏中不会出现的代码,帮助我验证隐藏的盒子。盒子的范围是1到5个,包括1到5个,并且每次游戏重新开始时都是随机的。我从guess-box开...
循环使用 else 语句 在python 中,while … else 在循环条件为 false 时执行 else 语句块: 实例 #!/usr/bin/pythoncount=0whilecount<5:printcount,"is less than 5"count=count+1else:printcount,"is not less than 5" 以上实例输出结果为: 0isless than51isless than52isless than53isless than54isle...

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...

The following while loop is an infinite loop, using True as the condition: x = 10; while (True): print(x) x += 1 Flowchart: Python: while and else statement There is a structural similarity between while and else statement. Both have a block of statement(s) which is only executed wh...
While loop is used to iterate over a block of code repeatedly until a given condition returns false. In the last tutorial, we have seen for loop in Python, which is also used for the same purpose. The main difference is that we use while loop when we are

Python uses the while and for keywords to constitute a conditional loop, by which repeated execution of a block of statements is done until the specified boolean expression is true. The following is the while loop syntax. Syntax: while [boolean expression]: statement1 statement2 ... statement...
