typeshed

Typeshed provides external type annotations for the Python standard library, built-in functions, and third-party packages, facilitating static analysis, type checking, type inference, and autocompletion. Notably, it supports Python versions 3.10 to 3.14 and includes contribution guidelines to ensure consistency and accuracy in type definitions. Users can leverage pre-bundled annotations with type checkers like mypy or install third-party stubs directly from PyPI for enhanced type compatibility.
