mypy
A static type checker for Python that enforces type hints to catch bugs before runtime.
What is mypy?
Mypy is a static type checker for Python that analyzes code for type errors before execution, using type hints (PEP 484) to ensure variables and functions are used correctly. It helps catch bugs early in the development cycle, such as unsupported operations between incompatible types, without interfering with the program's runtime behavior.
Python developers and teams looking to improve code reliability, maintainability, and scalability in large or complex codebases through static type analysis.
Developers choose Mypy for its powerful type system, gradual typing approach, and seamless integration with existing Python workflows, offering a balance between dynamic flexibility and static safety without requiring a full rewrite.
