/// info | Información

`Query`, `Path` y otras clases que verás más adelante son subclases de una clase común `Param`.

Todas ellas comparten los mismos parámetros para validación adicional y metadatos que has visto.

///

/// note | Detalles técnicos

Cuando importas `Query`, `Path` y otros de `fastapi`, en realidad son funciones.

Que cuando se llaman, retornan instances de clases con el mismo nombre.

Controlar todas as partes web centrais. Adiciona funcionalidades por cima.

A classe `FastAPI` em si herda diretamente da classe `Starlette`.

Então, qualquer coisa que você pode fazer com Starlette, você pode fazer diretamente com o **FastAPI**, pois ele é basicamente um Starlette com esteróides.

### Création d'un `Enum`

Importez `Enum` et créez une sous-classe qui hérite de `str` et `Enum`.

En héritant de `str` la documentation sera capable de savoir que les valeurs doivent être de type `string` et pourra donc afficher cette `Enum` correctement.

Créez ensuite des attributs de classe avec des valeurs fixes, qui seront les valeurs autorisées pour cette énumération.
