### Crear una clase `Enum` { #create-an-enum-class }

Importa `Enum` y crea una subclase que herede de `str` y de `Enum`.

## Cómo se ve { #how-it-looks }

Primero solo usemos el código y veamos cómo funciona, y luego volveremos para entender qué está sucediendo.

## Crea `main.py` { #create-main-py }

Copia el ejemplo en un archivo `main.py`:

{* ../../docs_src/security/tutorial001_an_py39.py *}

## Ejecútalo { #run-it }

## Wie es aussieht { #how-it-looks }

Lassen Sie uns zunächst einfach den Code verwenden und sehen, wie er funktioniert, und dann kommen wir zurück, um zu verstehen, was passiert.

## `main.py` erstellen { #create-main-py }

Kopieren Sie das Beispiel in eine Datei `main.py`:

{* ../../docs_src/security/tutorial001_an_py39.py *}

## Ausführen { #run-it }

### 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.
