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

Aber wenn wir das in der Zuweisung `response_model=PlaneItem | CarItem` machen, erhalten wir eine Fehlermeldung, da Python versucht, eine **ungültige Operation** zwischen `PlaneItem` und `CarItem` durchzuführen, statt es als Typannotation zu interpretieren.

## Listen von Modellen

Genauso können Sie eine Response deklarieren, die eine Liste von Objekten ist.

### 태그 사용

`tags` 매개변수를 *경로 작동* 및 `APIRouter`와 함께 사용하여 태그에 할당할 수 있습니다:

```Python hl_lines="21  26"
{!../../docs_src/metadata/tutorial004.py!}
```

/// info

태그에 대한 자세한 내용은 [경로 작동 구성](path-operation-configuration.md#tags){.internal-link target=_blank}에서 읽어보세요.

### 태그 순서

...경로는 다음과 같습니다:

```
/items/foo
```

/// info | "정보"

"경로"는 일반적으로 "엔드포인트" 또는 "라우트"라고도 불립니다.

API를 설계할 때 "경로"는 "관심사"와 "리소스"를 분리하기 위한 주요한 방법입니다.

#### 작동

"작동(Operation)"은 HTTP "메소드" 중 하나를 나타냅니다.

다음 중 하나이며:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...흔히 사용되지 않는 것들도 있습니다:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

	RET


// More JMP/JAL cases, and canonical names JMP, CALL.

	JAL	foo(SB) // CALL foo(SB)
	BEQ	R1, 2(PC)
	JMP	foo(SB)
	CALL	foo(SB)
	RET	foo(SB)

	// unary operation
	NEGW	R1, R2 // 00011023

	DSBH	R1, R2 // 7c0110a4

	SEB	R1, R2 // 7c011420
	SEH	R1, R2 // 7c011620

If one or more drives are offline at the start of a PutObject or NewMultipartUpload operation the object will have additional data protection bits added automatically to provide additional safety for these objects.
