"How to Use Static Typing in Python with Type Hints, MyPy and Pydantic"
summary
Demonstrates using type hints together with MyPy and Pydantic to catch real errors: MyPy performs static analysis and flags incompatible assignments (e.g., assigning an int to a hinted str or appending an int to List[str]), while Pydantic validates at runtime, auto-coercing numeric strings into floats by default but raising ValidationError when conversion fails or when strict=True is set. Shows concrete class examples (Rectangle area/perimeter) and recommends incremental adoption and using Pydantic at system boundaries.
