## Overview
|
|||
|
|
|
|||
|
|
The `typing_extensions` module serves two related purposes:
|
|||
|
|
|
|||
|
|
- Enable use of new type system features on older Python versions. 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.
|
|||
|
|
|
|||
|
|
