This link is a good resource:

Overview:

Module is simple .py file.
Package is a folder with group of .py files and __init.py__ like:

r2d2/
│
├── bootstrap/
│   ├── __init__.py
│   └── database.py
│   └── config.py
│   └── project.py
│
├── helpme/
│   ├── __init__.py
│   ├── organize.py
│
├── hotel/
│   ├── aareana.py
│   └── mantra.py
│   └── machester.py
│
└── __init__.py

However, the folder needs to be in PYTHONPATH so that the module can be used.
PYTHONPATH can be set by export PYTHONPATH="$HOME/repos/gitlab/chores/r2d2"
It can be tested by:

import sys 
print(sys.path)

Let’s create a package that will help me everyday works and call it r2d2
