### `Query`와 `Annotated` 임포트 { #import-query-and-annotated }

이를 위해 먼저 다음을 임포트합니다:

* `fastapi`에서 `Query`
* `typing`에서 `Annotated`

{* ../../docs_src/query_params_str_validations/tutorial002_an_py310.py hl[1,3] *}

/// info | 정보

FastAPI는 0.95.0 버전에서 `Annotated` 지원을 추가했고(그리고 이를 권장하기 시작했습니다).

이전 버전을 사용하면 `Annotated`를 사용하려고 할 때 오류가 발생합니다.

### `Query` と `Annotated` のインポート { #import-query-and-annotated }

そのために、まずは以下をインポートします:

* `fastapi` から `Query`
* `typing` から `Annotated`

{* ../../docs_src/query_params_str_validations/tutorial002_an_py310.py hl[1,3] *}

/// info | 情報

FastAPI はバージョン 0.95.0 で `Annotated` のサポートを追加し（推奨し始め）ました。

古いバージョンの場合、`Annotated` を使おうとするとエラーになります。
