### Erstellen Sie eine `Enum`-Klasse

Importieren Sie `Enum` und erstellen Sie eine Unterklasse, die von `str` und `Enum` erbt.

Indem Sie von `str` erben, weiß die API Dokumentation, dass die Werte des Enums vom Typ `str` sein müssen, und wird in der Lage sein, korrekt zu rendern.

### Crea una clase `Enum`

Importa `Enum` y crea una sub-clase que herede desde `str` y desde `Enum`.

Al heredar desde `str` la documentación de la API podrá saber que los valores deben ser de tipo `string` y podrá mostrarlos correctamente.

### Bir `Enum` Sınıfı Oluşturalım

`Enum` sınıfını projemize dahil edip `str` ile `Enum` sınıflarını miras alan bir alt sınıf yaratalım.

### Criando uma classe `Enum`

Importe `Enum` e crie uma sub-classe que herde de `str` e de `Enum`.

Por herdar de `str` a documentação da API vai ser capaz de saber que os valores devem ser do tipo `string` e assim ser capaz de mostrar eles corretamente.
