This error message tells us there is a problem on line 3, something to do
with the int() method call.

You have posted a number of posts this week, and it feels like you write a
bunch of code, run into a problem, then post it without trying to figure it
out.  I don't mean to offend, but really, many of your questions are pretty
basic:
- how do I use regex's (to extract data from an easily split string of
space-delimited numbers)?
- how do I round a number?
- I get this traceback, what's wrong with my program?
Please read up on the Python tutorials, and learn how to use the interactive
help.

Overall, c.l.py is pretty newbie-friendly, and a "n00b" question every so
often is no big deal - but you've got to make more of an effort yourself.
There is also a tutorial mailing list that is - I started to say "more
geared for beginners", but we have plenty of lurker beginners on c.l.py, I'm
sure - I'd say the tutorial mailing list is more willing to handhold new
Python programmers.

And a posted "thanks" once in a while is not bad etiquette either.
