```Python hl_lines="9-13"

In versions of Python below Python 3.9 you import `Annotated` from `typing_extensions`.

It will already be installed with FastAPI.

```Python hl_lines="3-4"
{!> ../../docs_src/query_params_str_validations/tutorial002_an.py!}
```

////

/// info

FastAPI added support for `Annotated` (and started recommending it) in version 0.95.0.

If you have an older version, you would get errors when trying to use `Annotated`.

В версиях Python ниже Python 3.9 `Annotation` импортируется из `typing_extensions`.

Эта библиотека будет установлена вместе с FastAPI.
