typeshed
A collection of external type annotations (stubs) for the Python standard library and third-party packages.
What is typeshed?
Typeshed is a collection of external type annotations (stub files) for Python's standard library and third-party packages. It provides the type definitions that static type checkers and IDEs use to perform type checking, inference, and autocompletion on Python code, solving the problem of missing or incomplete type hints in libraries.
Python developers using static type checkers (like mypy or pyright) or IDEs with type support, as well as library maintainers who want to provide or consume type annotations for their packages.
Developers choose Typeshed because it offers a centralized, community-driven source of high-quality type stubs that are essential for accurate static analysis, reducing type-related errors and improving developer productivity across the Python ecosystem.
