## Mehr Motivation

Sehen Sie sich diese Funktion an, sie hat bereits Typhinweise:

```Python hl_lines="1"
{!../../../docs_src/python_types/tutorial003.py!}
```

    ```Python hl_lines="3  17"
    {!> ../../../docs_src/path_operation_configuration/tutorial001.py!}
    ```

=== "Python 3.9 and above"

    ```Python hl_lines="3  17"
    {!> ../../../docs_src/path_operation_configuration/tutorial001_py39.py!}
    ```

=== "Python 3.10 and above"

    ```Python hl_lines="1  15"
    {!> ../../../docs_src/path_operation_configuration/tutorial001_py310.py!}
    ```
