Tatsächlich gibt es in einigen Fällen sogar **zwei JSON-Schemas** in OpenAPI für dasselbe Pydantic-Modell für Eingabe und Ausgabe, je nachdem, ob sie **Defaultwerte** haben.

Sehen wir uns an, wie das funktioniert und wie Sie es bei Bedarf ändern können.

## Pydantic-Modelle für Eingabe und Ausgabe

Nehmen wir an, Sie haben ein Pydantic-Modell mit Defaultwerten wie dieses:

=== "Python 3.10+"

    ```Python hl_lines="7"

  c. Copyright and Similar Rights means copyright and/or similar rights
     closely related to copyright including, without limitation,
     performance, broadcast, sound recording, and Sui Generis Database
     Rights, without regard to how the rights are labeled or
     categorized. For purposes of this Public License, the rights
     specified in Section 2(b)(1)-(2) are not Copyright and Similar
     Rights.

=== "Python 3.8+"

    ```Python hl_lines="1  8"
    {!> ../../../docs_src/extra_models/tutorial005.py!}
    ```

## Zusammenfassung

Verwenden Sie gerne mehrere Pydantic-Modelle und vererben Sie je nach Bedarf.

* Machen Sie sich auch keine Sorgen über Stilregeln, es gibt bereits automatisierte Tools, die das überprüfen.

Und wenn es irgendeinen anderen Stil- oder Konsistenz-Bedarf gibt, bitte ich direkt darum oder füge zusätzliche Commits mit den erforderlichen Änderungen hinzu.
