Review code and organize/change to match Python coding guidelines

[deoren]

I'm guilty of not following these due to old habits with C, Perl, etc.

http://bayes.colorado.edu/PythonGuidelines.html
http://www.python.org/dev/peps/pep-0008/
http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html

Not all of those may apply (non python.org links), but look to be useful.

Unfortunately my old notes are thin on this one, but moving it across just to be consistent.
