For example,\n  `typing.TypeGuard` is new in Python 3.10, but `typing_extensions` allows\n  users on previous Python versions to use it too.\n- Enable experimentation with new type system PEPs before they are accepted and\n  added to the `typing` module.\n\n`typing_extensions` is treated specially by static type checkers such as\nmypy and pyright. Objects defined in `typing_extensions` are treated the same\nway as equivalent forms in `typing`.\n\n`typing_extensions` uses\n[Semantic Versioning](https://semver.org/). The\nmajor version will be incremented only for backwards-incompatible changes.\nTherefore, it's safe to depend\non `typing_extensions` like this: `typing_extensions \u003e=x.y, \u003c(x+1)`,\nwhere `x.y` is the first version that includes all features you need.\n\n## Included items\n\nSee [the documentation](https://typing-extensions.readthedocs.io/en/latest/#) for a\ncomplete listing of module contents.\n\n## Contributing\n\nSee [CONTRIBUTING.md](https://github.com/python/typing_extensions/blob/main/CONTRIBUTING.md)\nfor how to contribute to `typing_extensions`.\n","funding_links":["https://www.python.org/psf/donations/python-dev/","https://github.com/sponsors/python"],"categories":["Python","Backports and improvements"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpython%2Ftyping_extensions","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpython%2Ftyping_extensions","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpython%2Ftyping_extensions/lists"}
