## Descrição avançada a partir de docstring

Você pode limitar as linhas utilizadas a partir de uma docstring de uma *função de operação de rota* para o OpenAPI.

Adicionar um `\f` (um caractere de escape para alimentação de formulário) faz com que o **FastAPI** restrinja a saída utilizada pelo OpenAPI até esse ponto.

Ele não será mostrado na documentação, mas outras ferramentas (como o Sphinx) serão capazes de utilizar o resto do texto.

## Pydantic 모델

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>은 데이터 검증(Validation)을 위한 파이썬 라이브러리입니다.

당신은 속성들을 포함한 클래스 형태로 "모양(shape)"을 선언할 수 있습니다.

그리고 각 속성은 타입을 가지고 있습니다.

이 클래스를 활용하여서 값을 가지고 있는 인스턴스를 만들게 되면, 필요한 경우에는 적당한 타입으로 변환까지 시키기도 하여 데이터가 포함된 객체를 반환합니다.

그리고 결과 객체에 대해서는 에디터의 도움을 받을 수 있게 됩니다.

Pydantic 공식 문서 예시:

# but POSIX shell has neither arrays nor command substitution, so instead we
# post-process each arg (as a line of input to sed) to backslash-escape any
# character that might be a shell metacharacter, then use eval to reverse
# that process (while maintaining the separation between arguments), and wrap
# the whole thing up as a single "set" statement.
