Well, if you're guessing which part of your code is slow, you should
profile your code so you can stop guessing.  Python has some very
useful built in profiling tools, documented here:
http://docs.python.org/lib/profile.html

Take a look at the "Instant User's Manual", which should be enough to
get you started. Once you can see exactly which parts of your code are
taking the longest, then you'll know what the best targets are for
optimization.
