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 repository is used for several things:

Historically, this repository hosted a backport of the typing module for older Python versions. The last released version, supporting Python 2.7 and 3.4, is available at PyPI.
