Mais malheureusement, rien d'utile n'en résulte :

### Ajouter des types

Modifions une seule ligne de la version précédente.

Nous allons changer seulement cet extrait, les paramètres de la fonction, de :


```Python
    first_name, last_name
```

à :

```Python
    first_name: str, last_name: str
```

C'est tout.

    Então, é uma função geradora que transfere o trabalho de "geração" para alguma outra coisa interna.

    Fazendo dessa forma, podemos colocá-la em um bloco `with`, e assim garantir que o objeto semelhante a um arquivo é fechado quando a função termina.

Por ejemplo:

* **Visión por computadora**: una imagen está compuesta de millones de píxeles, cada píxel tiene 3 valores / colores, procesar eso normalmente requiere calcular algo en esos píxeles, todos al mismo tiempo.

## `Annotated`인 의존성 공유하기

위의 예제에서 몇몇 작은 **코드 중복**이 있다는 것을 보았을 겁니다.

`common_parameters()`의존을 사용해야 한다면, 타입 명시와 `Depends()`와 함께 전체 매개변수를 적어야 합니다:

```Python
commons: Annotated[dict, Depends(common_parameters)]
```

하지만 `Annotated`를 사용하고 있기에, `Annotated` 값을 변수에 저장하고 여러 장소에서 사용할 수 있습니다:

{* ../../docs_src/dependencies/tutorial001_02_an_py310.py hl[12,16,21] *}
