KeyboardInterrupt is just an exception that gets raised when CTLR+C (or 
the OS's equivalent keyboard combo) gets pressed. It can occur at any 
point in a script since you never know when the user will press it, which 
is why you put the try: except KeyboardInterrupt: around as much of your 
script as possible.  The signal that the OS sends to the Python 
interpreter is irrelevant.
