That will work as intended, if you had your original `except
KeyboardInterrupt, error:` and did a `print repr(error)` afterwards you
will see it does not contain an error message as you perhaps wanted.
Also, Python does not require semi-colons to denote the end-of-line. It
can be used if you want to have multiple statements on a single line though.
