You should use multiple modules to separate the code where it makes
sense, along *conceptual* lines. Make separate modules that each
represent a conceptually-separate area of functionality in your
application, and put the classes which implement that functionality in
that module.

You can start by making one module for each of those groupings. (The
term “package” already has a specific technical meaning in Python, and
I'm not sure whether that's what you meant here.)
