Edit: Actually, while reading one of the sample chapters it becomes apparent that this book is more of a general introduction to programming than a book about learning Python. I also noticed that there are a few notes sprinkled here and there about changes in python 3.0. So I withdraw my previous criticism.
Also: kudos for getting the SouthPark reference about the rectal probe in there :)
I think the best way is to convert the PDF to the Mobi format with the free mobipocket creator:

The conversion works pretty well and if you have patience you can even generate things like table of contents and proper metadata.
Edit: you may also know that oreilly sells an ebook "package" with books in the following formats: Android, Mobi, PDF, ePub. For example:
http://oreilly.com/catalog/9780596158071/
(I'm not affiliated with oreilly in any way)
Programming Python http://shop.oreilly.com/product/9780596158118.do
and
Learning Python http://shop.oreilly.com/product/9780596158071.do
Not sure where I fall with these books in terms of skill and knowledge. Looking through the table of contents for Learning Python I recognize everything and know what they are, but don't have a great masterful grasp of most of the stuff but I am afraid too much of it will be stuff I already know. On the flip side, Programming Python might be too advanced for me.
EDIT Seems Programming Python is mainly geared towards Python 3.x but I'm still using 2.6.
