What each one is

The product in its own terms, so the numbers below have context.

Black

An opinionated Python code formatter that automatically reformats code according to a standardized style. It produces minimal diffs for cleaner code review and reduces developer cognitive load by removing formatting decisions, allowing focus on code logic.

Independently observed

mypy

A type analysis tool for Python that enables code to transition from pure dynamic typing to statically-typed code through annotations, with error detection at check time. Code runs with negligible performance impact and developers can incrementally adopt static types in existing projects.
