## Datenklassen in verschachtelten Datenstrukturen { #dataclasses-in-nested-data-structures }

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

In einigen Fällen müssen Sie möglicherweise immer noch Pydantics Version von `dataclasses` verwenden. Zum Beispiel, wenn Sie Fehler in der automatisch generierten API-Dokumentation haben.

Descubrí Molten en las primeras etapas de construcción de **FastAPI**. Y tiene ideas bastante similares:

* Basado en las anotaciones de tipos de Python.
* Validación y documentación a partir de estos tipos.

* Validação e documentação a partir desses tipos.

    * 因此透過使用 FastAPI，你可以節省開發時間、錯誤與程式碼數量，並且相比不使用 FastAPI 你很大可能會獲得相同或更好的效能（因為那樣你必須在程式碼中實現所有相同的功能）。

    * 因此，通过使用 FastAPI 意味着您可以节省开发时间，减少编码错误，用更少的编码实现其功能，并且相比不使用 FastAPI 您很大可能会获得相同或更好的性能（因为那样您必须在代码中实现所有相同的功能）。

Although in FastAPI it's optional, and is used mainly to set headers, cookies, and alternative status codes.

I discovered Molten in the first stages of building **FastAPI**. And it has quite similar ideas:

* Based on Python type hints.
* Validation and documentation from these types.
* Dependency Injection system.
