마찬가지로 예제에서 `tags`를 구체적으로 "문자열의 리스트"로 만들 수 있습니다:

```Python hl_lines="14"
{!../../docs_src/body_nested_models/tutorial002.py!}
```

## 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:

```Python hl_lines="1  14"
{!../../docs_src/body_nested_models/tutorial003.py!}
```
