따라서 `Query`를 사용하면서 값을 필수로 선언해야 할 때는, 기본값을 선언하지 않으면 됩니다:

{* ../../docs_src/query_params_str_validations/tutorial006_an_py310.py hl[9] *}

### 필수지만 `None` 가능 { #required-can-be-none }

매개변수가 `None`을 허용하지만 여전히 필수라고 선언할 수 있습니다. 이렇게 하면 값이 `None`이더라도 클라이언트는 값을 반드시 전송해야 합니다.

이를 위해 `None`이 유효한 타입이라고 선언하되, 기본값은 선언하지 않으면 됩니다:
