/// note | 참고

`response_model`은 "데코레이터" 메소드(`get`, `post`, 등)의 매개변수입니다. 모든 매개변수들과 본문(body)처럼 *경로 작동 함수*가 아닙니다.

///

Pydantic 모델 어트리뷰트를 선언한 것과 동일한 타입을 수신하므로 Pydantic 모델이 될 수 있지만, `List[Item]`과 같이 Pydantic 모델들의 `list`일 수도 있습니다.

FastAPI는 이 `response_model`를 사용하여:

* 출력 데이터를 타입 선언으로 변환.
* 데이터 검증.
* OpenAPI *경로 작동*의 응답에 JSON 스키마 추가.
* 자동 생성 문서 시스템에 사용.

하지만 가장 중요한 것은:

This means:

* The variable `prices` is a `dict`:
    * The keys of this `dict` are of type `str` (let's say, the name of each item).
    * The values of this `dict` are of type `float` (let's say, the price of each item).

#### Union { #union }

You can declare that a variable can be any of **several types**, for example, an `int` or a `str`.
