## 집합 타입

그런데 생각해보니 태그는 반복되면 안 되고, 고유한(Unique) 문자열이어야 할 것 같습니다.

그리고 파이썬은 집합을 위한 특별한 데이터 타입 `set`이 있습니다.

그렇다면 `Set`을 임포트 하고 `tags`를 `str`의 `set`으로 선언할 수 있습니다:

{* ../../docs_src/body_nested_models/tutorial003.py hl[1,14] *}

덕분에 중복 데이터가 있는 요청을 수신하더라도 고유한 항목들의 집합으로 변환됩니다.

그리고 해당 데이터를 출력 할 때마다 소스에 중복이 있더라도 고유한 항목들의 집합으로 출력됩니다.
