Best book on Python?

[BJörn Lindqvist]

I haven't read any Python paper books myself but as Christmas is
coming up, I've checked up on what Python books other people
recommend. Everyone who has reviewed Python books seem to like these
books:

* Python Essential Reference
* Python Cookbook
* Python in a Nutshell

The last two are both written by Alex Martelli and the cookbook is
IMHO really awesome.
