Typeshed is a collection of static type stubs for the Python standard library, builtins, and many third-party packages. It provides the annotations consumed by type checkers like mypy, pyright, and PyCharm for static analysis, type inference, and autocompletion.

Use cases

• add static type checking to Python code
• get autocompletion and type inference in an IDE
• install type stubs for third-party packages like requests
• build a custom Python type checker or static analysis tool
• fix incorrect type annotations for a Python library

When to choose

• you need type annotations for the Python standard library or builtins
• a third-party package lacks inline types and you need stubs
• you are developing a type checker or static analysis tool for Python

When to avoid

• you just use a type checker and don't need to modify stubs (they are bundled/installed automatically)
• you need runtime behavior rather than static type information
• the library already ships its own inline type annotations
