While loop– This loop statement checks for a condition at the beginning and till the condition is fulfilled, it will execute the body of the loop. For loop– For loops are used to sequentially iterate over a python sequence. When the sequence has been iterated completely, the for loop ends...
whilelooppython-python中while和forloop的应用 for适用于你知道要循环多少次的情况 while通常是动态判定是否需要继续执行,就这样~两个都是通用的,因为for可以用break跳出 pythonwhile循环的用法是什么? pythonwhile循环语句: 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...
while陳述句(statement)所建立的迴圈不像for迴圈,需要在一定的範圍內迭代;也不像if陳述句,只存在執行一次或不執行的狀況。只要陳述的條件為真True,while迴圈就會持續到天荒地老,或者電腦當掉。 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...

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个...

The Python while loop: you'll learn how you can construct and use a while loop in data science applications. You'll do this by going over some interactive coding challenges. Next, you'll move on to the for loop: once again, you'll learn how you can construct and use a for loop in...
Python for loop vs while loop Thefor loopis usually used in the sequence when the number of iterations is known. For example, # loop is iterated 4 timesforiinrange(4):print(i) Run Code Output 0 1 2 3 Thewhileloop is usually used when the number of iterations is unknown. For example...
