## Objective

Run [mypy](https://mypy.readthedocs.io/en/stable/) on your Python code to perform static typing
checks, ensuring better code reliability and readability. `mypy` is a Python tool that checks the
types of variables, function return values, and more.

### Global Configuration of mypy

To add configuration to `mypy` shared with any other usage of mypy (such as manual run, pre-commit,
etc), you can use `mypy.ini`, `setup.cfg` or `pyproject.toml` configuration file. Learn more
about [mypy configuration](https://mypy.readthedocs.io/en/stable/config_file.html) files.

## How to use it

1. Configure the `mypy.ini`, `setup.cfg` or `pyproject.toml` file in your repository's root directory with your
   desired rules.
2. Include the mypy template in your CI/CD configuration (see quick use above).
3. If you need to customize the job, check
   the [jobs customization](https://docs.r2devops.io/get-started/use-templates/#job-templates-customization).
