MyPy is the premier static type checker for Python. While running MyPy with no configuration works, achieving true, robust type safety requires a configuration that enables strict mode and specifically targets potential weak points in Python's type system.

This article details the essential settings within the mypy.ini, pyproject.toml, or setup.cfg file that an experienced developer uses to maximize type checking effectiveness.

The difference between "Python hints" and "typing hints" is primarily one of scope and terminology, rather than distinct technologies.

In short: Typing hints are a subset of Python hints.

The combination of the standard enum.Enum class and the typing module is a powerful best practice in modern Python. By using an Enum class as a type hint, you signal to static type checkers (like MyPy, Pyright) and fellow developers that only specific, named constants are valid inputs or outputs, enforcing both type safety and value safety.
