What is __init__.py used for?

The __init__.py file is used to mark a directory as a Python package. This file is usually empty, but can be used to initialize the package or set certain variables.

For example, suppose you have a directory called my_package that contains several Python modules. To make this directory into a package, you would create an __init__.py file in the my_package directory. This would allow you to use the import statement to import modules from the my_package directory, like this:

import my_package.my_module

In this case, my_package is the package, and my_module is a module in the package. The __init__.py file allows you to organize your Python code into reusable packages and modules.
