Just a little bit for the basics -- this is a bit of an odd example, but should give you the idea if you're still not sure.

Alternatively, see if you can clean up some of your other code (mailroom, maybe) with Exception handling.

Improving input

• The input() function can generate two exceptions: EOFError or KeyboardInterrupt on end-of-file(EOF) or canceled input.
• Create a wrapper function, perhaps safe_input() that returns None rather rather than raising these exceptions, when the user enters ^C for Keyboard Interrupt, or ^D (^Z on Windows) for End Of File.
