Static Typing for Python

Documentation and Support

The documentation for Python's static typing can be found at typing.readthedocs.io. You can get help either in our support forum or chat with us on Gitter.

Improvements to the type system should be discussed on the typing-sig mailing list, although the issues in this repository contain some historic discussions.

Repository Content

This GitHub repo is used for several things:

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

• The typing_extensions module lives in the typing_extensions directory.

• The documentation at typing.readthedocs.io is maintained in the docs directory.

• A discussion forum for typing-related user help is hosted 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.
