=== "Python 3.8 nicht annotiert"

    !!! tip "Tipp"
        Bevorzugen Sie die `Annotated`-Version, falls möglich.

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

Sie deklarieren die Abhängigkeit als Typ des Parameters und verwenden `Depends()` ohne Parameter, anstatt die vollständige Klasse *erneut* in `Depends(CommonQueryParams)` schreiben zu müssen.
