    Se você nunca viu os `...` antes: é um valor único especial, faz <a href="https://docs.python.org/3/library/constants.html#Ellipsis" class="external-link" target="_blank">parte do Python e é chamado "Ellipsis"</a>.

Dessa forma o **FastAPI** saberá que o parâmetro é obrigatório.

    이전에 `...`를 본적이 없다면: 특별한 단일값으로, <a href="https://docs.python.org/3/library/constants.html#Ellipsis" class="external-link" target="_blank">파이썬의 일부이며 "Ellipsis"라 부릅니다</a>.

이렇게 하면 **FastAPI**가 이 매개변수는 필수임을 알 수 있습니다.

## 쿼리 매개변수 리스트 / 다중값

쿼리 매개변수를 `Query`와 함께 명시적으로 선언할 때, 값들의 리스트나 다른 방법으로 여러 값을 받도록 선언 할 수도 있습니다.
