```Python
some_variable: PlaneItem | CarItem
```

하지만 이를 `response_model=PlaneItem | CarItem`과 같이 할당하면 에러가 발생합니다. 이는 Python이 이를 타입 어노테이션으로 해석하지 않고, `PlaneItem`과 `CarItem` 사이의 **잘못된 연산(invalid operation)**을 시도하기 때문입니다

## 모델 리스트

마찬가지로, 객체 리스트 형태의 응답을 선언할 수도 있습니다.

이를 위해 표준 Python의 `typing.List`를 사용하세요(또는 Python 3.9 이상에서는 단순히 `list`를 사용할 수 있습니다):

Dieser Client könnte ein Browser mit einem Frontend sein, ein Code von jemand anderem, ein IoT-Gerät usw.

Sie könnten dem Client mitteilen müssen, dass:

* Der Client nicht genügend Berechtigungen für diese Operation hat.
* Der Client keinen Zugriff auf diese Ressource hat.
* Die Ressource, auf die der Client versucht hat, zuzugreifen, nicht existiert.
* usw.
