And these models are all sharing a lot of the data and duplicating attribute names and types.

We could do better.

We can declare a `UserBase` model that serves as a base for our other models. And then we can make subclasses of that model that inherit its attributes (type declarations, validation, etc).

## Starlette features

You couldn't get this kind of editor support if you were working directly with `dict` instead of Pydantic models.

But you don't have to worry about them either, incoming dicts are converted automatically and your output is converted automatically to JSON too.

## Bodies of arbitrary `dict`s

    Aber eine dotenv-Datei muss nicht unbedingt genau diesen Dateinamen haben.

Pydantic unterstützt das Lesen dieser Dateitypen mithilfe einer externen Bibliothek. Weitere Informationen finden Sie unter <a href="https://docs.pydantic.dev/latest/concepts/pydantic_settings/#dotenv-env-support" class="external-link" target="_blank">Pydantic Settings: Dotenv (.env) support</a>.

    In vielen Fällen kann OAuth2 mit Scopes ein Overkill sein.

    Aber wenn Sie wissen, dass Sie es brauchen oder neugierig sind, lesen Sie weiter.

## OAuth2-Scopes und OpenAPI

Die OAuth2-Spezifikation definiert „Scopes“ als eine Liste von durch Leerzeichen getrennten Strings.
