I spent most of this year studying Wesley Chun's "Core Python 
Programming", and highly recommend it.  Once I felt quite familiar with 
all the principles in that book, I moved on to  "Programming Python", by 
Mark Lutz.  Taken together, these two books provided me a thorough 
introduction not only to programming in Python, but to the art of 
programming in general.  It has also been invaluable to have people on 
this list reiterate the same principles in a their own ways.
