andwhile loopsin Python allows you to automate and efficiently repeat tasks. These loops are fundamental constructs in Python that enable you to iterate over sequences, such as lists, tuples, and strings, or to execute a block of code repeatedly based on a condition. However, there are scena...
-2 How do I exit a True loop and move on to the next piece of code in python? 0 How to exit a while loop when the input or variable in a user-defined function meets the condition in Python 1 Python 2.7: While loop, can't break out 0 How can you go out of a function i...
break 语句可以立即终止当前循环的执行,跳出当前所在的循环结构。无论是 while 循环还是 for 循环,只要执行 break 语句,就会直接结束当前正在执行的循环体。 这就好比在操场上跑步,原计划跑 10 圈,可是当跑到第 2 圈的时候,突然想起有急事要办,于是果断停止跑步并离开操场,这就相当于使用了 break 语句提前终止了...
下面这段代码演示了while循环的使用。程序首先要求输入5个数字,然后依次输出这5个数字。 # while循环numbers =input("输入几个数字,用逗号分隔:").split(",")print(numbers) x =0whilex <len(numbers):# 当x的值小于输入字数的个数的时候,执行循环内容print(numbers[x]) x +=1# 一个循环结束时给x加1 ...
循环语句是指重复执行同一段代码块,通常用于遍历集合或者累加计算。Python中的循环语句有while语句、for语句。 01 while循环 循环语句是程序设计中常用的语句之一。任何编程语言都有while循环,Python也不例外。while循环的格式如下所示。 while(表达式):...

In Python the break statement is used to exit a for or a while loop and the continue statement is used in a while or for loop to take the control to the top of the loop without executing the rest statements inside the loop.
