Why not?  Ctrl+Break, or more typically Ctrl-C, is the de facto standard 
approach for terminating a console (non-GUI) application.

In this case, just wrap the code with a "try/except KeyboardInterrupt" and
put your "stop and save" code in the except block.  (Note that Ctrl-Break
will bypass this, but Ctrl-C is caught as you would expect.)

Also, when posting questions of this nature it's a good idea explicitly 
to specify your platform (Linux, Windows, etc).
