PEP 484: Type Hints

This GitHub repo is used for three separate things:

  • The issue tracker is used to discuss PEP-level type system issues. However, typing-sig is more appropriate these days.

  • A backport of the typing module for older Python versions (2.7 and 3.4) is maintained here. Note that the canonical source lives upstream in the CPython repo.

  • The typing_extensions module lives here.

Workflow

  • See CONTRIBUTING.md for more.

  • The typing.py module and its unittests are edited in the src subdirectory of this repo. The python2 subdirectory contains the Python 2 backport.
