Wenn Sie eine zweiminütige Auffrischung benötigen, wie man Python-Typen verwendet (auch wenn Sie FastAPI nicht benutzen), schauen Sie sich das kurze Tutorial an: [Einführung in Python-Typen](python-types.md){.internal-link target=_blank}.

Sie schreiben Standard-Python mit Typen:

```Python
from datetime import date

from pydantic import BaseModel

# Deklarieren Sie eine Variable als ein str

Eine vielseitige Möglichkeit ist der <a href="https://openapi-generator.tech/" class="external-link" target="_blank">OpenAPI Generator</a>, der **viele Programmiersprachen** unterstützt und SDKs aus Ihrer OpenAPI-Spezifikation generieren kann.
