def nested_loops(): while True: # 外层循环 while True: # 内层循环 print("Inside inner loop") # 某些条件满足时,直接返回 if condition: return print("Inside outer loop") nested_loops() 在这个示例中,当condition满足时,使用return跳出函数,从而跳出所有嵌套的循环。 三、使用异常处理 另一种方法是...
exit_flag = True break if exit_flag: break print("循环结束") 在这个例子中,当i和j都等于1时,设置exit_flag为True,跳出内层循环,再通过外层循环的检查,终止外层循环。 2、通过函数跳出嵌套循环 可以将嵌套循环放在一个函数中,通过return语句来跳出所有嵌套循环。 def nested_loops(): for i in range(3)...

while 循环 在给定的判断条件为 true 时执行循环体,否则退出循环体。 for 循环 重复执行语句 嵌套循环 你可以在while循环体中嵌套for循环 1.2.循环控制语句 循环控制语句可以更改语句执行的顺序。Python支持以下循环控制语句: break结束全部循环,跳出整个循环 continue结束本次循环,进入下次循环 shell脚本里用break2可以...
Exit All Loops Python While Loop Termination Journey 旅行图清晰地展示了程序在循环执行和终止过程中的每个阶段。 结论 在Python 中,while循环是一个非常强大的工具,通过合适的控制和条件判断,我们可以成功地终止循环。无论是使用break语句还是通过设置全局状态来管理多个循环,理解这些机制对于有效编写程序至关重要。此...
Python while Loops: Repeating Tasks Conditionally In this quiz, you'll test your understanding of Python's while loop. This loop allows you to execute a block of code repeatedly as long as a given condition remains true. Understanding how to use while loops effectively is a crucial skill fo...
Python 2.5 While Loops while Loops#while循环 An if statement is run once if its condition evaluates to True, and never if it evaluates to False. A while statement is similar, except that it can be run more than once. The statements inside it are repeatedly executed, as long as the ...
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 » Note:remember to increment i, or else the loop will continue forev...
Python 为什么不设计 do-while 循环结构？现阶段在python实现do-while循环，我们只能是先定义“while Tru...
Python While 1 Run the example: In this code, we import time so we can use a “wait” function called sleep() . Then, we make a new variable called alive and set it to True. When you make a variable equal to True or False, you are making abooleanvariable. This means it can onl...
