What is a Python Module?

I think it's used in a very broad sense, but

From Official document

A module is a file containing Python definitions and statements.The filename is the module name with the suffix .py.

But it will be the first image to come.

Also, I think there are more situations where you use a module, but in that situation, you use import to import the module.

For example, if you want to use the command line input variables using the features defined in the sys module

import sys

print(sys.argv[0])

uses the functionality of the sys module.
