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 exhaustion of the list (with for) or when the condition ...
FOR_LOOP ||--o{ NESTED_LOOP : contains NESTED_LOOP ||--o{ BREAK_STATEMENT : uses 结尾 通过上述步骤和实例代码,你应该能够清晰地理解在Python的for循环结构中,如何有效地使用break语句来控制程序的执行流。无论是在简单的列表迭代,还是在复杂的嵌套循环中,合理使用break可以帮助你提高代码的效率和可读性。...

Python break Statement Example Gives is a Python program which iterates over the characters of sequence “Python”. The loop uses break statement to terminate immidiately as soon as character ‘h’ is encounterd in conditional expression of if statement. for s in "python": if s == "h":...
if (statement 2){ break if (statement 3){ } } 我有一个如上所示的伪代码,我想验证我的理解是否正确。是不是当statement 2完成时,第一个if loop中的等式还会运行,然后它就会打破if loop,再也不会回来了,即使while loop还在继续?在这个场景中,我正在寻求关于break函数的解释。 浏览23提问于2020-03-28得...
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 ...
