How to publish a private Python package to a package registry?

To publish a private Python package, first create a `setup.py` script for your package, allowing you to specify your package's metadata. Next, build a distribution package using the command below:

`python setup.py sdist`

Then, use a private package registry like PyPI's private repository or an internal package registry. Of course, make sure to upload your package using a tool like `twine`, providing authentication credentials for the private registry. Finally, configure your project's "requirements.txt" file to include the private package and distribute it to authorized team members. This way, your package remains private while accessible to the intended audience.
