Installing dependencies and installing your package

• py-project-template

It uses requirement.txt and pip which are the traditional/common choices. And setup.cfg as from my research that is also the popular/modern way to go. Use requirements-lock.txt if you care about subdependencies.

If you care about installing your project itself (not just its dependencies), so it can be installed by others for example, only then do you need to worry about setup.py.

See my installable package here:

• python-package-quickstart

Or

• setup.py

    #!/usr/bin/env python
    """
    Install my-app.
    """
  
    import setuptools
  
    setuptools.setup()
  

Some tools like poetry need pyproject.toml.

And if using Pipenv then use Pipfile and Pipfile.lock.
