Zum Beispiel:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

In diesem Fall ist `fluffy` eine Instanz der Klasse `Cat`.

Und um `fluffy` zu erzeugen, rufen Sie `Cat` auf.

Eine Python-Klasse ist also auch ein **Callable**.

Und dann wäre die Gunicorn-kompatible **Uvicorn-Worker**-Klasse dafür verantwortlich, die von Gunicorn gesendeten Daten in den ASGI-Standard zu konvertieren, damit FastAPI diese verwenden kann.

## Gunicorn und Uvicorn installieren

<div class="termy">

```console
$ pip install "uvicorn[standard]" gunicorn

---> 100%
```

### 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.

```Python hl_lines="1  6-9"
