install Ctrl-C handler

[Uwe Mayer]

Hi,

can anybody tell me how you install something like a Ctrl-C handler in
Python, i.e. a routine that is called when ^C is pressed and that can do
cleanup work?

Thanks
Uwe

Maybe you require something more sophisticated but ctrl-C raises an exception
that can be caught:
.... while 1: pass
.... except KeyboardInterrupt:
.... print 'Interrupted!'
....
Interrupted!

Interrupted!

Thinking about it, try-finally would also work:
.... while True: pass
.... finally:
.... print 'cleaning up'
....
cleaning up
Traceback (most recent call last):
File "<stdin>", line 2, in ?
KeyboardInterrupt

On *nix you can use the signal-module for general signal handling. There are
some caveats in multithreaded apps.
