Python Documentation
Current Python Documentation
Python's documentation is found online at docs.python.org, including all current translations.
Documentation for end-of-life Python releases
Older versions of the standard documentation are kept available as well, since many users have to maintain code for older versions of the interpreter as well. These can be found at https://www.python.org/doc/versions.html.
Other learning resources
https://www.python.org/doc/ lists other resources, including books and alternative introductory material.
