### Declare a `List` com um parâmetro de tipo

Para declarar tipos que têm parâmetros de tipo(tipos internos), como `list`, `dict`, `tuple`:

* Importe os do modulo `typing`
* Passe o(s) tipo(s) interno(s) como "parâmetros de tipo" usando colchetes: `[` e `]`

```Python
from typing import List

my_list: List[str]
```

Essa é a sintaxe padrão do Python para declarações de tipo.

    * `url` (**obrigatório**): uma `str` com a URL da documentação externa.

### Criar Metadados para tags

Vamos tentar isso em um exemplo com tags para `users` e `items`.

Crie metadados para suas tags e passe-os para o parâmetro `openapi_tags`:

{* ../../docs_src/metadata/tutorial004.py hl[3:16,18] *}

* Es muss kein tatsächlicher Code vorhanden sein, da Ihre Anwendung diesen Code niemals aufruft. Sie wird nur zur Dokumentation der *externen API* verwendet. Die Funktion könnte also einfach `pass` enthalten.
