    Falls Sie das `...` bisher noch nicht gesehen haben: Es ist ein spezieller einzelner Wert, <a href="https://docs.python.org/3/library/constants.html#Ellipsis" class="external-link" target="_blank">Teil von Python und wird „Ellipsis“ genannt</a> (Deutsch: Ellipse).

    Es wird von Pydantic und FastAPI verwendet, um explizit zu deklarieren, dass ein Wert erforderlich ist.
