Python X Library

It seems that there is a random mix of spaces and tabs
used for indentation, which makes the source look
screwed up if you don't use the same tab width as the
author(s) (8, I assume, as that is how wide python
considers a tab to be). Obviously this is not a huge
blatant bug, but more of a wishlist thing for the sake
of people who have the desire/need to look through the
code, which I assume is quite a few people using it.
