Python Tricks  (English, Paperback, Bader Dan)

Good one

Definitely worth it for the python devs just starting or for the devs looking for really interesting features in python that is less known.
For example ,i never knew that a function can be nested inside another or did u know that function can be stored in a list ,there's a lot to take .
Also u ll be able to learn some really cool concepts like decorators ,lambda ,just lots ....i am reading it from 1 week ,and I am already loving it.

It's a great book for intermediate level python programmers. As it not only explains concepts really well but also focuses a lot on writing beautiful rather than ugly. Great addition to anyone's Python Library.
