Ahora en lugar de devolver:

```json
{"message": "Hello World"}
```

...este response devolverá:

```json

  "message": "Hello World"
}
```

<a href="https://pydantic-docs.helpmanual.io/" class="external-link" target="_blank">Pydantic</a> ist eine Python-Bibliothek für die Validierung von Daten.

Sie deklarieren die „Form“ der Daten als Klassen mit Attributen.

Und jedes Attribut hat einen Typ.
