Oh, and not just bugs either. If the user hits Ctrl-C at just the
right moment, KeyboardInterrupt will be raised. You'll swallow that
exception silently, preventing the user-requested halt, and going and
doing the wrong thing. Don't use a bare except clause even if your
code is 100% perfect every time. (And anyone who thinks their code is
perfect hasn't tested it.)
