Good starterbook for learning Python?

[Luis M. Gonzalez]

Before buying a book, I suggest starting out with at least one of these
beginners tutorials available in internet:

- Non-Programmers Tutorial For Python by  Josh Cogliati
(honors.montana.edu/~jjc/easytut/easytut/)
- A Byte of Python by Swaroop CH (www.byteofpython.info)

There are many others, but these ones are very good. The first one is
best for someone who knows nothing about programing, and the second one
is probably better for you, since you already have some experience.
It's good for absolute beginners though.

Books:
- Learning Python by Mark Lutz
- Core Python by Wesley Chun
