Python入门之break和ontinue语句，以及else运用于循环语句 The break statement, like in C, breaks out of the innermost enclosing for or while loop.Python中断语句与C语言类似，打破了最小封闭for或while循环。Loop statements may have an else clause; it is executed when the loop terminates through exhaust...
# python example of break statement count = 1 num = 0 choice = 0 while True: # input the number num = int(input("Enter a number: ")) # break if num is 0 if num==0: break # terminates inner loop # print the table count = 1 while count<=10: print(num*count) count += 1...
The break statement in Python terminates the nearest enclosing loop prematurely. This tutorial explains how to use break to exit loops, demonstrates nested loop scenarios, and provides practical examples of flow control. When executed, break immediately stops loop iteration and transfers execution to ...
Python'sbreakstatement allows you to exit the nearest enclosingwhileorforloop. Often you'llbreakout of a loop based on a particular condition, like in the following example: s = 'Hello, World!' for char in s: print(char) if char == ',': break ...
Python Copy以上代码输出结果为:1 2 3 Loop finished. Bash Copy在这个例子中,我们使用了while循环,当i小于或等于5时,执行循环体内的代码。我们使用if语句来检查是否达到3,如果达到3,我们使用break语句停止循环。在循环结束后,我们输出一条消息。break语句的应用场景break能够应用到很多的场景,比如说:在循环中查找元...

简述break语句用于提前终止当前循环。放弃循环后,继续执行下一条语句,就像 C 中传统的 break 语句一样。 break 最常见的用途是当某些外部条件被触发需要从循环中快速退出时。这break语句可用于while和for循环。 如果您正在使用嵌套循环,则 break 语句会停止最内层循环 .

然而,我的“else”本意是for循环的else子句,而不是if/else的else。http://book.pythontips.com/en/latest/for_-_else.html - Shushiro 那么你就不需要else语句了。让我更新我的答案。 - Noooo 1 其他答案已经很好地解释了如何跳出多个循环。但是你也可以通过使用Python的内置函数和列表推导式来简化代码,像这...
