    ```Python
    commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
    ```

=== "Python 3.8+ non-Annotated"

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

    ```Python
    commons: CommonQueryParams = Depends(CommonQueryParams)
    ```

...you write:

=== "Python 3.8+"

    ```Python
    commons: Annotated[CommonQueryParams, Depends()]

## Аннотация типа или `Depends`

Обратите внимание, что в приведенном выше коде мы два раза пишем `CommonQueryParams`:

=== "Python 3.6+ без Annotated"

    !!! tip "Подсказка"
        Рекомендуется использовать версию с `Annotated` если возможно.

    ```Python
    commons: CommonQueryParams = Depends(CommonQueryParams)
    ```

    val commonsCodec = "commons-codec:commons-codec"
    val commonsCompress = "org.apache.commons:commons-compress"
    val commonsHttpclient = "org.apache.httpcomponents:httpclient"
    val commonsIo = "commons-io:commons-io"
    val commonsLang = "commons-lang:commons-lang"
    val commonsLang3 = "org.apache.commons:commons-lang3"
    val commonsMath = "org.apache.commons:commons-math3"

**FastAPI** ruft die Klasse `CommonQueryParams` auf. Dadurch wird eine „Instanz“ dieser Klasse erstellt und die Instanz wird als Parameter `commons` an Ihre Funktion überreicht.

## Typannotation vs. `Depends`

Beachten Sie, wie wir `CommonQueryParams` im obigen Code zweimal schreiben:

=== "Python 3.8+"

    ```Python
    commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
    ```

=== "Python 3.8+ nicht annotiert"
