Wenn Sie eine große Anwendung haben, können sich am Ende **viele Tags** anhäufen, und Sie möchten sicherstellen, dass Sie für verwandte *Pfadoperationen* immer den **gleichen Tag** nehmen.

In diesem Fall macht es Sinn, die Tags in einem `Enum` zu speichern.

**FastAPI** unterstützt diese genauso wie einfache Strings:
