In my opinion, the python official documents, include the tutorial, language reference, library reference, distributing python modules, also extending and embedding, Python/C API, are all what you need to learn python and use it, as long as you can read into it. Also you can read other python programs. If you want to know more you can read the cpython source itself. Its not too difficult.
