What each one is
The product in its own terms, so the numbers below have context.
Black
A Python code formatter that automatically reformats entire files to enforce consistent styling. It produces minimal diffs to accelerate code review and ensures uniform appearance across projects.
mypy
A static type checker that analyzes Python code to catch type errors before runtime. Supports gradual typing, allowing you to mix static and dynamic typing and incrementally add type hints to existing codebases.
