Literature if you want to get better at using the language and gain a deeper understanding of it: "Effective Python" and "Serious Python". Also have a look at the Python standard library documentation and e.g. the data model documentation, plus the release notes of recent Python versions (e.g. pattern matching). Tons of interesting material there.

Hands-on stuff: Write command-line tools and libraries that are useful for yourself or that are somehow fun. Try out some existing or 3rd party libraries.
