# Static Typing for Python

## Documentation and Support

The documentation for Python's static typing can be found at

[typing.readthedocs.io](https://typing.readthedocs.io/). You can get

help in our [support forum](https://github.com/python/typing/discussions).

Improvements to the type system should be discussed on

[Python's Discourse](https://discuss.python.org/c/typing/32), and are

tracked in the [issues](https://github.com/python/typing/issues) in this

repository.

For conversations that are more suitable to a chat platform, you can use one of the following:

- [gitter](https://gitter.im/python/typing)

- [discord](https://discord.com/channels/267624335836053506/891788761371906108) `#type-hinting` channel

## Repository Content

This GitHub repository is used for several things:

- The documentation at [typing.readthedocs.io](https://typing.readthedocs.io/)

  is maintained in the [docs directory](./docs). This includes the

  [specification](https://typing.readthedocs.io/en/latest/spec/index.html) for the

  type system. See especially [the update procedure](https://typing.readthedocs.io/en/latest/spec/meta.html)

  for the spec.

- A [discussion forum](https://github.com/python/typing/discussions) for typing-related user

  help is hosted here.

- [Conformance test](https://github.com/python/typing/blob/main/conformance/README.md) for Python static type checkers. The [latest conformance test results](https://htmlpreview.github.io/?https://github.com/python/typing/blob/main/conformance/results/results.html) are here.

Historically, this repository also hosted:

- The `typing_extensions` package, which now lives in the

  [typing_extensions](https://github.com/python/typing_extensions) repo.

  It used to be in the `typing_extensions` directory.

- A backport of the

  [`typing` module](https://docs.python.org/3/library/typing.html) for older

  Python versions. It was removed after all Python versions that lack `typing`

  in the standard library reached end of life. The last released version,

  supporting Python 2.7 and 3.4,

  is [available at PyPI](https://pypi.org/project/typing/).
