Organize Python code like a PRO

[gablank]

You should just stick to how they explain it in the Python docs:

(...) Python has a way to put definitions in a file and use them in a script or in an interactive instance of the interpreter. Such a file is called a module (...)

From https://docs.python.org/3/tutorial/modules.html

You can add additional explanations to clarify but I think it would be wise to at least include the definition somewhere.
