```

The code following the `yield` statement is executed after the response has been delivered:

```Python hl_lines="5-6"
{!../../../docs_src/dependencies/tutorial007.py!}
```

!!! tip
    You can use `async` or regular functions.

    **FastAPI** will do the right thing with each, the same as with normal dependencies.

## A dependency with `yield` and `try`

## Without Pydantic

                The function to call after the response is sent.

                It can be a regular `def` function or an `async def` function.
                """
            ),
        ],
        *args: P.args,
        **kwargs: P.kwargs,
    ) -> None:
        """

class UploadFile(StarletteUploadFile):
    """
    A file uploaded in a request.

    Define it as a *path operation function* (or dependency) parameter.

    If you are using a regular `def` function, you can use the `upload_file.file`
    attribute to access the raw standard Python file (blocking, not async), useful and
    needed for non-async code.

Por exemplo, extendendo o modelo anterior, você poder decidir por ter uma outra chave `importance` no mesmo corpo, além de `item` e `user`.

Se você declará-lo como é, porque é um valor singular, o **FastAPI** assumirá que se trata de um parâmetro de consulta.

Mas você pode instruir o **FastAPI** para tratá-lo como outra chave do corpo usando `Body`:

=== "Python 3.8+"

    ```Python hl_lines="22"

Und jetzt hat dieses neue `examples`-Feld Vorrang vor dem alten (und benutzerdefinierten) `example`-Feld, im Singular, das jetzt deprecated ist.

Dieses neue `examples`-Feld in JSON Schema ist **nur eine `list`e** von Beispielen, kein Dict mit zusätzlichen Metadaten wie an den anderen Stellen in OpenAPI (oben beschrieben).
