"The Django Book"

today i've found very interesting thing on wired.com - book about Django. it looks very good and it is free.
recently, i'm trying to learn Python. for me it's very interesting computer language and there are my interesting features (lambda function, collections and other). very important is that this language is very simple to learn.
all what i can said about this language is that i like it and it willl be my first language for writing simple things (today i'm using php and sometimes perl).
