Hi. :)
I'm whipping up a program in Python and am having to deal with a user
potentially hitting ctrl-c at any point in the program. I'd like my
Python program to wrap up cleanly when it receives this signal.
I did some Googling and read that Python throws a KeyboardInterrupt
error. What's the best way to run a specific "cleanup" function at
*any* time the interrupt is received, regardless of where the program
is in execution?
Most of the stuff I've read involves try-except blocks. This makes
sense to me if I want to protect a specific function or area of the
code from being interrupted by ctrl-c, but I'm not sure what kind of
structure my program must have to catch the exception at any point
during execution.
Thoughts/ideas appreciated. :)
Thanks!
