## `Union`, oder `anyOf`

Sie können deklarieren, dass eine Response eine <abbr title="Union – Verbund, Einheit‚ Vereinigung: Eines von Mehreren">`Union`</abbr> mehrerer Typen ist, sprich, einer dieser Typen.

Das wird in OpenAPI mit `anyOf` angezeigt.

    {!> ../../../docs_src/body/tutorial001.py!}
    ```

## Erstellen Sie Ihr Datenmodell

Dann deklarieren Sie Ihr Datenmodell als eine Klasse, die von `BaseModel` erbt.

Verwenden Sie Standard-Python-Typen für die Klassenattribute:

=== "Python 3.10+"

    ```Python hl_lines="5-9"
    {!> ../../../docs_src/body/tutorial001_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="7-11"
