For example, `typing.TypeGuard` is new in Python 3.10, but `typing_extensions` allows users on previous Python versions to use it too. - Enable experimentation with new type system PEPs before they are accepted and added to the `typing` module. `typing_extensions` is treated specially by static type checkers such as mypy and pyright. Objects defined in `typing_extensions` are treated the same way as equivalent forms in `typing`. `typing_extensions` uses [Semantic Versioning](https://semver.org/). The major version will be incremented only for backwards-incompatible changes. Therefore, it's safe to depend on `typing_extensions` like this: `typing_extensions >=x.y, <(x+1)`, where `x.y` is the first version that includes all features you need. `typing_extensions` supports Python versions 3.7 and higher. ## Included items See [the documentation](https://typing-extensions.readthedocs.io/en/latest/#) for a complete listing of module contents. ## Contributing See [CONTRIBUTING.md](https://github.com/python/typing_extensions/blob/main/CONTRIBUTING.md) for how to contribute to `typing_extensions`.
