在普通的Python程序中,使用exit()函数可以立即终止程序的执行。 exit在while循环中的使用 在while循环中,我们可以通过捕获SystemExit异常来实现在循环中提前退出的效果。下面是一个简单的示例代码: whileTrue:try:user_input=input("Enter 'exit' to stop the loop: ")ifuser_input=='exit':exit()exceptSystemExit...

Python -while、for、continue、break语句 一、while 语句 作用:while 语句用于循环执行程序,在某条件下为真时,循环执行程序段,经常用来处理需要重复相同的任务。 格式: while 判断条件: 执行语句 只有判断条件为真,就执行语句,执行完语句后,继续判断条件是否为真,直到条件为假时,退出,执行后面的代码。 有时: whil...
其中,exit for loop语句是一个非常有用的关键字,它允许在某个条件满足时提前退出循环。 本文将逐步回答关于Robot Framework中的exit for loop语句的相关问题,以帮助读者更好地理解和使用这个功能。 1. Robot Framework中的循环结构和关键字 在Robot Framework中,有两种常见的循环结构:For循环和While循环。 # 1.1 ...
