You really are new at this, aren't you? ;-) You need to import the sys
module before you use it. Put this at the top of your script:

import sys

I'd also suggest that you have a run through the tutorial -
<http://docs.python.org/tut/>. It's time well spent. If you don't get
on with that, there's another couple of tutorials available aimed
directly at those new to programming -
<http://www.livewires.org.uk/python/> and
<http://www.ibiblio.org/obp/thinkCSpy/>.

Lastly, although neophytes are more than welcome here, you might find
the tutor mailing list a good place to ask questions in the early days
of your Python experience. You'll find it here -
<http://mail.python.org/mailman/listinfo/tutor>.
