What is a Python module?

Patrick:
I'm working on a description of a Python module. So far, I see it as a file that is a repository
of a collection of user-defined functions. The module is not generally a runnable program,
but rather is intended to be imported into some python program. I suppose the purpose of
modules is to declutter any given python program, while allowing the programmer to build
his or her own `library' of functions that can be used (by importing) in multiple programs.

Copilot:
You're spot-on with your understanding of Python modules! Here's a refined version of your
description that you might find helpful:

A Python module is a file containing a collection of user-defined functions, classes, and
variables. Its primary purpose is not to be executed as a standalone program, but rather to
be imported and utilized within other Python programs. By encapsulating reusable code, modules
help to declutter programs, promote code organization, and foster the creation of a personal
library of functions that can be leveraged across multiple projects.
