Best place to learn advanced python?

pyvideo.org if you are a self learner

If you know basics think about some complex project, without finding out proper solutions, make list of features you would like to have, then try to code it. You will find out that many things are not easy to achive, require libraries etc and don't forget about unit tests, docstrings and documentation.

For me, that was best way to increase my skill level.

In Python what you want to learn? In web - shanti, flask, etc
Machine learning, ai, assembly, hacking, networking or core Python with data structure and all

Library, I'd guess.
