### `HeroPublic`으로 단일 Hero 조회하기

단일 hero을 **조회**할 수도 있습니다:

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[75:80] hl[77] *}

### `HeroUpdate`로 Hero 수정하기

**hero를 수정**할 수도 있습니다. 이를 위해 HTTP `PATCH` 작업을 사용합니다.

코드에서는 클라이언트가 보낸 데이터를 딕셔너리 형태(`dict`)로 가져옵니다. 이는 **클라이언트가 보낸 데이터만 포함**하며, 기본값으로 들어가는 값은 제외합니다. 이를 위해 `exclude_unset=True`를 사용합니다. 이것이 주요 핵심입니다. 🪄
