!!! tip

You can adapt it to any other NoSQL database like:

* **MongoDB**
* **Cassandra**
* **CouchDB**
* **ArangoDB**
* **ElasticSearch**, etc.

    ```

This will make `tags` be a list, although it doesn't declare the type of the elements of the list.

## List fields with type parameter

But Python has a specific way to declare lists with internal types, or "type parameters":

### Import typing's `List`

In Python 3.9 and above you can use the standard `list` to declare these type annotations as we'll see below. 💡

## 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.

## List of models

The same way, you can declare responses of lists of objects.

For that, use the standard Python `typing.List` (or just `list` in Python 3.9 and above):

=== "Python 3.9+"

    ```Python hl_lines="18"
    {!> ../../../docs_src/extra_models/tutorial004_py39.py!}

    "bar"
  ]
}
```

#### 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.

**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.

!!! tip "Astuce"

        query_params: Optional[List[ModelField]] = None,
        header_params: Optional[List[ModelField]] = None,
        cookie_params: Optional[List[ModelField]] = None,
        body_params: Optional[List[ModelField]] = None,
        dependencies: Optional[List["Dependant"]] = None,
        security_schemes: Optional[List[SecurityRequirement]] = None,
        name: Optional[str] = None,
