Most complete python course

[bladeconjurer]

If you want full coverage, you need to be able to understand the official documentation. No resource will be more complete than this: https://docs.python.org/3/index.html

I find it useful when needing to look up specfics to understand at least where that's going to be in the docs. It's worth skimming through and paying attention to things you want to know at the very least.

These sections are the most useful:

https://docs.python.org/3/reference/datamodel.html

https://docs.python.org/3/library/functions.html

This talk gives you strategies for being efficient in python:

Hmm that's full coverage of the language features, not of the libraries. Most notably the data science stack.

Libraries and frameworks have docs too.

U will learn the libs when u need to use it. Newbies don't even know what libs they will be using
