I personally like the big white "CORE Python Programming" book. It's 
easy to read, and it gives you a good grasp of the basics of the 
language when you're done, even if you haven't touched a keyboard. After 
that, I recommend the Python Recipies book, which gets into the details 
of how things need to be done to do it efficiently. For example:

data=""
while 1:
   data+=infile.readline()
   ...

is an O(N^2) operation. (hmm, N^N? Anyways, really bad.)

data=[]
while 1:
   data+=[infile.readline()]
   ...
data="".join(data)
is O(N)
