Para lograr eso, primero importa:

* `Query` desde `fastapi`
* `Annotated` desde `typing`

{* ../../docs_src/query_params_str_validations/tutorial002_an_py310.py hl[1,3] *}

/// info | Información

FastAPI añadió soporte para `Annotated` (y empezó a recomendarlo) en la versión 0.95.0.

Si tienes una versión más antigua, obtendrás errores al intentar usar `Annotated`.

### Exécuter l'application { #run-the-app }

Vous pouvez exécuter l'application :

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Lorsque vous travaillez sur des projets Python, vous devriez probablement utiliser un environnement virtuel (ou un mécanisme similaire) pour isoler les packages que vous installez pour chaque projet.

/// info

Si vous connaissez déjà les environnements virtuels, comment les créer et les utiliser, vous pouvez passer cette section. 🤓

/// tip | Astuce

my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

/// info

`**second_user_data` signifie :

Passez les clés et valeurs du dictionnaire `second_user_data` directement comme arguments clé-valeur, équivalent à : `User(id=4, name="Mary", joined="2018-11-30")`

보통 다음과 같이 특정 보안 권한을 선언하는 데 사용합니다:

* `users:read` 또는 `users:write` 는 흔한 예시입니다.
* `instagram_basic` 는 Facebook/Instagram에서 사용합니다.
* `https://www.googleapis.com/auth/drive` 는 Google에서 사용합니다.

OAuth2에서 “스코프”는 필요한 특정 권한을 선언하는 문자열일 뿐입니다.

`:` 같은 다른 문자가 있거나 URL이어도 상관없습니다.

그런 세부사항은 구현에 따라 달라집니다.

OAuth2 입장에서는 그저 문자열입니다.

* Un parámetro de query opcional `skip` que es un `int`, y por defecto es `0`.
* Un parámetro de query opcional `limit` que es un `int`, y por defecto es `100`.

Y luego solo devuelve un `dict` que contiene esos valores.
