How to end a python program while it is running?

Question

I study python by myself. And i got a problem here.."The human player may also end the game by pressing the Control-D sequence at any time." How can i do this.what kind of function should i use? Thanks.

Answer 1

You could try sys.exit() :

import sys
...
sys.exit()

There is also a more standard exit() function (for which you don't need to import anything). However there is one notable difference between this and sys.exit() as noted in the documentation:

Since exit() ultimately "only" raises an exception, it will only exit the process when called from the main thread, and the exception is not intercepted.

Answer 2

The basic logic here is to handle SIGQUIT keyboard interrupt. There are many kind of interrupts, Ctrl+C (SIGINT), Ctrl+D (SIGQUIT), etc. This SOF thread discusses catching Ctrl+C signal in python. Based on the same lines, its not hard to catch Ctrl+D. This python documentation provides more insights.
