What is Module?
A Python file containing definitions and statements that can be imported and reused in other Python programs.
A module is simply a .py file. It can define functions, classes, and variables. Modules promote code reuse and organization. Import with import module_name or from module import function.
Python comes with a rich standard library of modules (os, sys, json, datetime, etc.). Third-party modules are installed via pip. Packages are directories of modules with an __init__.py file.
