Die Datenklasse wird automatisch in eine Pydantic-Datenklasse konvertiert.

Auf diese Weise wird deren Schema in der Benutzeroberfläche der API-Dokumentation angezeigt:

<img src="/img/tutorial/dataclasses/image01.png">

## Datenklassen in verschachtelten Datenstrukturen

Sie können `dataclasses` auch mit anderen Typannotationen kombinieren, um verschachtelte Datenstrukturen zu erstellen.

{* ../../docs_src/dataclasses/tutorial002.py hl[1,7:13,19] *}

The dataclass will be automatically converted to a Pydantic dataclass.

This way, its schema will show up in the API docs user interface:

## Dataclasses in Nested Data Structures

You can also combine `dataclasses` with other type annotations to make nested data structures.
