在这个例子中,我们定义了一个自定义异常StopAllLoops。当内层循环满足条件时,抛出该异常。然后在最外层的try块中捕获这个异常,从而跳出所有循环。 示例代码: 下面是一个使用标志位变量来跳出所有循环的示例代码: python break_flag = False for i in range(2): for j in range(3): if j == 1: break_fl...
Pythonbreakstatement is used to exit from the for/while loops in Python. For loop iterates blocks of code until the condition isFalse. Sometimes you need to exit a loop completely or when you want to skip a current part of thepython for loopand go for the next execution without exiting ...
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 ...
For any strings that contain ani,breakexits ourfor char in string:loop. As this is our inner-most loop, Python then moves onto the next item in thefor string in strings:loop. Example 3: Break infinite Loops It's worth noting that if Python doesn't terminatewhileloops, they can loop en...
Here, we have two loops, outer loop is "while True:" which is handling the multiple inputs and inner loop is using to print the table of given number – as input is 0 – inner loop will be terminated. # python example of break statement count = 1 num = 0 choice = 0 while True...
例子: Python continue What is the use of break and continue in Python? In Python, break and continue statements can alter the flow of a normal loop. Loops iterate over a block of code until test expression is false, but sometimes we wish to terminate the current iteration or even the who...

Notice that the inner loop stops a ‘b’ without printing ‘c’ and ‘d’. The outer loop however prints all its elements. This is how the Python Break statement works in nested loops. Now, we move on to the continue statement
