Python setuptools How to define installation time conditional dependencies for dist package

Setuptools is a popular tool for building and distributing Python packages. It allows you to define dependencies that your package needs, and these dependencies can be installed automatically when someone installs your package. However, sometimes you may want to specify dependencies that are only required under certain conditions. This tutorial will show you how to define installation-time conditional dependencies for your Python distribution package using Setuptools.

If you haven't already, create your Python package. You should have a project structure similar to this:
In this example:
To install your package along with conditional dependencies, users can specify the extras they want during installation using square brackets. For example:
This command will install 'my_package' along with the 'extra_dependency' if the 'optional_feature' extra is requested.
To install 'my_package' with 'dev' extras:
This allows your code to be flexible and adapt to the presence or absence of conditional dependencies.
