{!> ../../../docs_src/path_operation_configuration/tutorial004_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="19-27"
    {!> ../../../docs_src/path_operation_configuration/tutorial004_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="19-27"
    {!> ../../../docs_src/path_operation_configuration/tutorial004.py!}
    ```

In der interaktiven Dokumentation sieht das dann so aus:

    {!> ../../../docs_src/path_operation_configuration/tutorial004_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="19-27"
    {!> ../../../docs_src/path_operation_configuration/tutorial004_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="19-27"
    {!> ../../../docs_src/path_operation_configuration/tutorial004.py!}
    ```

Он будет использован в интерактивной документации:

## Как это использовать

Теперь вы можете объявить свою зависимость, используя этот класс.

=== "Python 3.10+"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial002_an_py39.py!}
    ```

=== "Python 3.6+"

    ```Python hl_lines="20"

      24, 21, 22, 23, 23, 21, 21, 22, 21, 23, 22, 23, 23, 20, 22, 22, 22, 23, 22, 22, 23, 26,
      26, 20, 19, 22, 23, 22, 25, 26, 26, 26, 27, 27, 26, 24, 25, 19, 21, 26, 27, 27, 26, 27,
      24, 21, 21, 26, 26, 28, 27, 27, 27, 20, 24, 20, 21, 22, 21, 21, 23, 22, 22, 25, 25, 24,
      24, 26, 23, 26, 27, 26, 26, 27, 27, 27, 27, 27, 28, 27, 27, 27, 27, 27, 26,
    )

  private val root = Node()

## Use it

Now you can declare your dependency using this class.

=== "Python 3.10+"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial002_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="20"

    ```

=== "Python 3.8+"

    ```Python hl_lines="19-21"
    {!> ../../../docs_src/body_multiple_params/tutorial001_an.py!}
    ```

=== "Python 3.10+ non-Annotated"

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="17-19"
    {!> ../../../docs_src/body_multiple_params/tutorial001_py310.py!}
    ```

* 기본값이 `100`이면서 `정수형`인 쿼리 매개변수 `limit`

두 가지 방식 모두, 데이터는 변환, 검증되고 OpenAPI 스키마에 문서화됩니다.

## 사용해봅시다!

이제 아래의 클래스를 이용해서 의존성을 정의할 수 있습니다.

=== "파이썬 3.6 이상"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial002.py!}
    ```

=== "파이썬 3.10 이상"

    ```Python hl_lines="17"
    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
    ```

=== "Python 3.10+"

    ```Python hl_lines="18-19"
    {!> ../../../docs_src/extra_data_types/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="18-19"
    {!> ../../../docs_src/extra_data_types/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="19-20"
    {!> ../../../docs_src/extra_data_types/tutorial001_an.py!}
    ```

注意，函数内的参数有原生的数据类型，你可以，例如，执行正常的日期操作，如:

=== "Python 3.10+"

    ```Python hl_lines="18-19"
    {!> ../../../docs_src/extra_data_types/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="18-19"
    {!> ../../../docs_src/extra_data_types/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="19-20"
    {!> ../../../docs_src/extra_data_types/tutorial001_an.py!}
    ```

=== "Python 3.10+"

    ```Python hl_lines="19-22  26-27"
    {!> ../../../docs_src/security/tutorial002_an_py310.py!}
    ```
