Many classes are kept in separate files, meaning they work just like a Python module. However, not all classes are modules, and likewise, classes can be included in-line in the main flow of your code.

Python’s been around in one form or another for over 30 years. Over that time, it has accumulated a wide and powerful set of modules in its standard library.

Python uses TOML, or Tom’s Obvious Minimal Language, as a configuration format (as in pyproject.toml), but doesn’t expose the ability to read TOML-format files as a standard library module.
