How to create a basic python module

Nowadays on times of python 3.14.X there are a tone of ways to create a python module. This is kind of the "old" way. You will be find python purist that say why this is no longer recommended, but I decide to document this version here because it is the current way of installing modules that works out-of-the-box with Yocto and with legacy tools. Besides the blog post Is setup.py deprecated? shows why this is still relevant and how it could be used to follow the latest trends.

$ tree py-project
├── py-project
│   ├── __init__.py
│   ├── ...
│   └── ...
├── README.md
└── setup.py

On the py-project folder should be the name of your module and then all your fancy stuffs for that module inside. The setup.py looks very basic something like this:

from setuptools import setup

setup(
    name='py-project',
    description="Awesome module of py-project",
    version='0.0.1',
    package_data={'py-project': ['< Here can be static files >']},
    install_requires=[
        'jsonschema>=4.24.0' # Example of required libraries
    ],
)

If you use a normal install command of pip, you will get a warning saying that you are not following the new standard on module creation. You can avoid that by using the flag --use-pep517 and --no-build-isolation.

# On root of module
$ pip install --use-pep517 --no-build-isolation .
