With Python, you can use while loops to run the same task multiple times and for loops to loop once over list data. In this module, you'll learn about the two loop types and when to apply each.Learning objectives After you've completed this module, you'll be able to: Identify when ...
Both loops can include nested loops, and you can use the continue and break statements to control the flow within them. Understanding these differences will help you choose the appropriate loop for your specific needs in Python programming.

Another common and extended use case of while loops in Python is to create event loops, which are infinite loops that wait for certain actions known as events. Once an event happens, the loop dispatches it to the appropriate event handler. Some classic examples of fields where you’ll find ...
Python中跳出while循环的方法有几种:使用break语句、使用return语句、修改循环条件。其中,使用break语句是最常见且直接的方法。在while循环内部,当满足某个条件时,使用break语句可以立即终止循环,跳出while循环体。例如,当你在编写一个无限循环时,可以通过检测某个条件并执行break语句来退出循环。
