Any non-trivial python module is going to be broken up into multiple files and have an __init__.py which you can explicitly define what's imported and exposed.

Any non-trivial python module is going to be broken up into multiple files and have an __init__.py which you can explicitly define what's imported and exposed. You can hoist a single file module into a folder-based module if you need direct control and don't want to split it apart into multiple files yet too.
