How does the extensions.py work within python package-CodePudding

I am reading other people's code and found extensions.py in their package. I can see the modules imported in the extensions.py are imported in init.py as well. I could not find how the extensions.py works with init.py and in what situation you need to use the extensions.py. Could anyone give me some explaination or provide some link that explain it?

In init.py

 from flask_app.extensions import cors, guard

In extension.py

from flask_praetorian import Praetorian
   cors = CORS()
   guard = Praetorian()

According to Python’s package tutorial this is the minimal structure:


packaging_tutorial/
├── LICENSE
├── pyproject.toml
├── README.md
├── setup.cfg
├── src/
│   └── example_package/
│       ├── __init__.py
│       └── example.py
└── tests/

Seems as its just a backup for installing requirements, or for more readability. Maybe provide where you found extensions.py, and I can take a deeper look.

You could also dig deeper into docs and see exactly what flask-praetorian does.

I think It's just a backup for installing things like requirements.
