## 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!}
```

덕분에 중복 데이터가 있는 요청을 수신하더라도 고유한 항목들의 집합으로 변환됩니다.

supports multiple KMS implementations via our [KES](https://github.com/minio/kes#kes) project. We run a KES instance at `https://play.min.io:7373` for you to experiment and quickly get started. To run MinIO with a KMS just fetch the root identity, set the following environment variables and then start your MinIO server. If you haven't installed MinIO, yet, then follow the MinIO [install instructions](https://min.io/docs/minio/linux/index.html#quickstart-for-linux) first.
