Current documentation
Python's documentation is found online at docs.python.org, including all current translations.
End-of-life 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 resources
The [[https://www.python.org/doc/|Python website] lists other resources, including books and alternative introductory material.
