/**

Und Sie können auch Body-Parameter als optional kennzeichnen, indem Sie den Defaultwert auf `None` setzen:

{* ../../docs_src/body_multiple_params/tutorial001_an_py310.py hl[18:20] *}

/// note | Hinweis

Beachten Sie, dass in diesem Fall das `item`, welches vom Body genommen wird, optional ist. Da es `None` als Defaultwert hat.

///

## Mehrere Body-Parameter

{* ../../docs_src/body_updates/tutorial002_py310.py hl[33] *}

### Rekapitulation zum teilweisen Ersetzen

Zusammengefasst, um Teil-Ersetzungen vorzunehmen:

* (Optional) verwenden Sie `PATCH` statt `PUT`.
* Lesen Sie die bereits gespeicherten Daten aus.
* Fügen Sie diese in ein Pydantic-Modell ein.
* Erzeugen Sie aus dem empfangenen Modell ein `dict` ohne Defaultwerte (mittels `exclude_unset`).

And you can also declare body parameters as optional, by setting the default to `None`:

{* ../../docs_src/body_multiple_params/tutorial001_an_py310.py hl[18:20] *}

/// note

Notice that, in this case, the `item` that would be taken from the body is optional. As it has a `None` default value.
