#### Utilizando `Union` ou `Optional` { #using-union-or-optional }

Se você está utilizando uma versão do Python abaixo da 3.10, aqui vai uma dica do meu ponto de vista bem **subjetivo**:

* 🚨 Evite utilizar `Optional[SomeType]`
* No lugar, ✨ **use `Union[SomeType, None]`** ✨.

### Importar las dependencias { #import-the-dependencies }

Este código vive en el módulo `app.routers.items`, el archivo `app/routers/items.py`.

Y necesitamos obtener la función de dependencia del módulo `app.dependencies`, el archivo `app/dependencies.py`.

* `description`
* `deprecated`

Validaciones específicas para strings:

* `min_length`
* `max_length`
* `pattern`

Validaciones personalizadas usando `AfterValidator`.

En estos ejemplos viste cómo declarar validaciones para valores de tipo `str`.
