이는 "`one_person`은 `Person` 클래스의 **인스턴스**"라는 뜻입니다.

"`one_person`은 `Person`이라는 **클래스**다"라는 뜻이 아닙니다.

## Pydantic 모델 { #pydantic-models }

[Pydantic](https://docs.pydantic.dev/)은 데이터 검증을 수행하는 파이썬 라이브러리입니다.

속성을 가진 클래스 형태로 데이터의 "모양(shape)"을 선언합니다.

그리고 각 속성은 타입을 가집니다.

Adoptar temporalmente este punto de vista (del *desarrollador externo*) puede ayudarte a sentir que es más obvio dónde poner los parámetros, el modelo de Pydantic para el body, para el response, etc. para esa *API externa*.
