`FastAPI` est une classe Python qui fournit toutes les fonctionnalités nécessaires au lancement de votre API.

/// note | Détails techniques

`FastAPI` est une classe héritant directement de `Starlette`.

Vous pouvez donc aussi utiliser toutes les fonctionnalités de <a href="https://www.starlette.dev/" class="external-link" target="_blank">Starlette</a> depuis `FastAPI`.

///

///

Execute o exemplo com:

<div class="termy">

```console
$ fastapi dev main.py

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

</div>

### Crie uma classe `Enum` { #create-an-enum-class }

Importe `Enum` e crie uma subclasse que herde de `str` e de `Enum`.

Ao herdar de `str`, a documentação da API saberá que os valores devem ser do tipo `string` e poderá renderizá-los corretamente.

Em seguida, crie atributos de classe com valores fixos, que serão os valores válidos disponíveis:
