```Python
user_dict = user_in.dict()
UserInDB(**user_dict)
```

äquivalent zu:

```Python
UserInDB(**user_in.dict())
```

... weil `user_in.dict()` ein `dict` ist, und dann lassen wir Python es „entpacken“, indem wir es `UserInDB` übergeben, mit vorangestelltem `**`.

Wir erhalten also ein Pydantic-Modell aus den Daten eines anderen Pydantic-Modells.

Sie würden also sehr früh im Entwicklungszyklus **viele Fehler erkennen**, anstatt darauf warten zu müssen, dass die Fehler Ihren Endbenutzern in der Produktion angezeigt werden, und dann zu versuchen, zu debuggen, wo das Problem liegt. ✨...
