Notice how we write `CommonQueryParams` twice in the above code:

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]

注意上面程式碼裡我們寫了兩次 `CommonQueryParams`：

//// tab | Python 3.10+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]

//// tab | Python 3.10+ 非 Annotated

如有可能，優先使用 `Annotated` 版本。

### `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.

## 匯入 `Path` { #import-path }

首先，從 `fastapi` 匯入 `Path`，並匯入 `Annotated`：

FastAPI 在 0.95.0 版加入並開始推薦使用 `Annotated`。

如果你使用更舊的版本，嘗試使用 `Annotated` 會出錯。

請確保在使用 `Annotated` 前，先[升級 FastAPI 版本](../deployment/versions.md#upgrading-the-fastapi-versions)到至少 0.95.1。
