结束无限的while循环 [英] Ending an infinite while loop

问题描述

我目前拥有基本运行无限while循环以从用户收集数据的代码.根据文本文件的内容不断更新字典/列表.供参考:

I currently have code that basically runs an infinite while loop to collect data from users. Constantly updating dictionaries/lists based on the contents of a text file. For reference:

while (True):
    IDs2=UpdatePoints(value,IDs2)
    time.sleep(10)

基本上，我的问题是我不知道何时结束，但是在运行while循环之后，我想使用收集的信息，而不会因为程序崩溃而丢失信息.是否有一种简单，优雅的方法可以在我需要的时候简单地退出while循环?像按键盘上的某个键一样棒.

Basically, my problem is that I do not know when I want this to end, but after this while loop runs I want to use the information collected, not lose it by crashing my program. Is there a simple, elegant way to simply exit out of the while loop whenever I want? Something like pressing a certain key on my keyboard would be awesome.

推荐答案

您可以尝试将代码包装在try/except块中，因为键盘中断只是个例外:

You can try wrapping that code in a try/except block, because keyboard interrupts are just exceptions:

try:
    while True:
        IDs2=UpdatePoints(value,IDs2)
        time.sleep(10)
except KeyboardInterrupt:
    print('interrupted!')

然后您可以使用CTRL-C退出循环.

Then you can exit the loop with CTRL-C.
