Par exemple, pour déclarer une autre réponse avec un code HTTP `404` et un modèle Pydantic `Message`, vous pouvez écrire :

{* ../../docs_src/additional_responses/tutorial001.py hl[18,22] *}

/// note | Remarque

Gardez à l'esprit que vous devez renvoyer directement `JSONResponse`.

La clé `model` ne fait pas partie d'OpenAPI.

```Python
print(user_dict)
```

würden wir ein Python-`dict` erhalten mit:

```Python
{
    'username': 'john',
    'password': 'secret',
    'email': '******@****.***',
    'full_name': None,
}
```

#### Ein `dict` entpacken { #unpacking-a-dict }

```Python
print(user_dict)
```

мы можем получить `dict` с такими данными:

```Python
{
    'username': 'john',
    'password': 'secret',
    'email': '******@****.***',
    'full_name': None,
}
```

#### Распаковка `dict` { #unpacking-a-dict }
