Data Structures in Python

I have been learning on a strictly learn as per requirement basis. Hence I have only the basic knowledge of python.

While working on django, I now feel the need to learn about data structures as now the nuances of lists, dictionaries, tuples etc. are coming into play and I'd like to become more comfortable with them. So here it goes into my priority list.

P.S. I've always wanted to learn more of data structures and algorithms. One has come into play, I hope the other will follow soon (if ever!).
