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...
To ensure that the loop terminates naturally, you should add one or more break statements wrapped in proper conditions: Python Syntax while True: if condition_1: break ... if condition_2: break ... if condition_n: break This syntax works well when you have multiple reasons to end the...
While loopLoops are used to repeatedly execute a block of program statements. 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 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。
Python while循环继续超出while条件 我的while循环并没有在应该停止的时候停止。显然,我这里缺少了一些基本的东西。 这是我的代码: import time import datetime import pandas as pd period = 5 start = pd.to_datetime('2022-01-01') end_final = pd.to_datetime('2022-01-31')...

else:可以在循环后使用,如果循环因为条件变为假而退出,则执行else块中的代码。 示例:else 语句 python for i in range(5): print(i) else: print("Loop finished") 在Python中,循环是编程的基础部分,通过合理使用for和while循环,可以实现复杂的逻辑和数据处理。
