!!! note "Nota"
    O comando `uvicorn main:app` se refere a:

    * `main`: o arquivo `main.py` (o "módulo" Python).
    * `app`: o objeto criado no arquivo `main.py` com a linha `app = FastAPI()`.

When you need to use the `common_parameters()` dependency, you have to write the whole parameter with the type annotation and `Depends()`:

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

But because we are using `Annotated`, we can store that `Annotated` value in a variable and use it in multiple places:

=== "Python 3.10+"

    So, it's really important that you actually read and run the code, and let me know in the comments that you did. 🤓

## `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:

=== "Python 3.10+"

<summary>À propos de la commande <code>uvicorn main:app --reload</code> ...</summary>

La commande `uvicorn main:app` fait référence à :

* `main` : le fichier `main.py` (le "module" Python).
* `app` : l'objet créé à l'intérieur de `main.py` avec la ligne `app = FastAPI()`.

```console
// Use the command "build-all", this will take a bit
$ python ./scripts/docs.py build-all

Building docs for: en
Building docs for: es
Successfully built docs for: es
```

</div>

这样会对每一种语言构建一个独立的文档站点，并最终把这些站点全部打包输出到 `./site/` 目录。



然后你可以使用命令 `serve` 来运行生成的站点：

<div class="termy">

```console
// Use the command "serve" after running "build-all"

<span style="color: green;">INFO</span>:     Waiting for application startup.
<span style="color: green;">INFO</span>:     Application startup complete.
