## Usando el `jsonable_encoder` en una `Response`

Como **FastAPI** no realiza ningún cambio en la `Response` que devuelves, debes asegurarte de que el contenido está listo.

Por ejemplo, no puedes poner un modelo Pydantic en una `JSONResponse` sin primero convertirlo a un `dict` con todos los tipos de datos (como `datetime`, `UUID`, etc) convertidos a tipos compatibles con JSON.

#### Utiliser `list`

Il est aussi possible d'utiliser directement `list` plutôt que `List[str]` :

```Python hl_lines="7"
{!../../../docs_src/query_params_str_validations/tutorial013.py!}
```

!!! note
    Dans ce cas-là, **FastAPI** ne vérifiera pas le contenu de la liste.

```Python
my_list: list[str]
```

Und in Python-Versionen vor 3.9:

```Python
from typing import List

my_list: List[str]
```

Das ist alles Standard-Python-Syntax für Typdeklarationen.

Verwenden Sie dieselbe Standardsyntax für Modellattribute mit inneren Typen.

In unserem Beispiel können wir also bewirken, dass `tags` spezifisch eine „Liste von Strings“ ist:

=== "Python 3.10+"

    ```Python hl_lines="12"

    # to be read from files and other types, but I'm not even sure it's a good idea
    # to support it as a first class "feature"
    assert is_bytes_sequence_annotation(Union[List[str], List[bytes]])


def test_is_uploadfile_sequence_annotation():
    # For coverage
    # TODO: in theory this would allow declaring types that could be lists of UploadFile

!!! tip

`response_model` receives the same type you would declare for a Pydantic model field, so, it can be a Pydantic model, but it can also be, e.g. a `list` of Pydantic models, like `List[Item]`.

FastAPI will use this `response_model` to do all the data documentation, validation, etc. and also to **convert and filter the output data** to its type declaration.

!!! tip

**FastAPI** possède une grande communauté en constante extension.

Il existe de nombreux articles, outils et projets liés à **FastAPI**.

Voici une liste incomplète de certains d'entre eux.

#### Usando `list`

Você também pode utilizar o tipo `list` diretamente em vez de `List[str]`:

```Python hl_lines="7"
{!../../../docs_src/query_params_str_validations/tutorial013.py!}
```

!!! note "Observação"
    Tenha em mente que neste caso, o FastAPI não irá validar os conteúdos da lista.
