Essential
So I borrowed my roomate's copy of "Python, Essential Reference" by David Beazley to see how it stackes up against O'Reillys "Python Standard Library", and I can say without a doubt that Essential Reference is the book that Standard Library should have been but wasn't.
Those that know me have probably been witness to my loathing of O'Reillys aweful Python books (with the exception of "Learning Python"). Standard Library covered it's bases, but I couldn't ever really think of it as a step up from the online documentation for Python. Essential Reference on the other hand is exactly what I want. It has COMPLETE attribute and fuction listings, reference tables that make sense, and sample code that illustrates things in a useful way. I may keep the Standard Library book, but I intend to buy myself a copy of Essential Reference ASAP.
