Hello,

I'm new to python and pretty new to programming in general. As a first
project, I'm trying to write a program to pull data from tables on webpages.
I'm having trouble with the HTMLParser module. Below is my code and the error
message. I'm thinking I should be using the debugger for this, but I don't
have a clue where to start so I'm emailing the list instead. Thanks in
advance. Also, this is my first email to a list like this one, so I'm
wondering if I'm observing proper social conventions. This message feels kind
of long to me. What do you think?
