Great free Python book for programmers

If you're already comfortable with the bsic concepts of programming (data types, operators, functions, OO, etc) then this free book may be a great way to get into Python:

I've just finished reading it and working through the examples and I'm already writting various useful scripts in Python (such as Python extensions for gEdit, amongst other nifty tricks).

Highly recommended! :)
