I exit () a script, but it does NOT exit

I am trying to exit the script, but it does not exit.

Here is my code:

import sys try: ... print "I'm gonna die!" sys.exit() except: ... print 'Still alive!'

And the results:

 I'm gonna die! Still alive!

Why?

If you really need to exit immediately and want to skip normal exit processing, you can use os._exit(status) . But, as others have said, it is usually best to go out of the normal way and just not catch the SystemExit exception. And while we're in the subject, KeyboardInterrupt is another exception that you might not want to catch. (Using except Exception will not capture either SystemExit or KeyboardInterrupt .)
