    ```Python
    with open("file.txt") as file:
        file.read()
    ```
    
    Nas versões mais recentes de Python, há também um **gerenciador de contexto assíncrono**. Você o usaria com `async with`:
    
    ```Python
    async with lifespan(app):
        await do_stuff()
    ```

  4. docs/en/docs/tutorial/testing.md

    !!! tip
        If you want to call `async` functions in your tests apart from sending requests to your FastAPI application (e.g. asynchronous database functions), have a look at the [Async Tests](../advanced/async-tests.md){.internal-link target=_blank} in the advanced tutorial.

    !!! tip "Tipp"
        Wenn Sie in Ihren Tests neben dem Senden von Anfragen an Ihre FastAPI-Anwendung auch `async`-Funktionen aufrufen möchten (z. B. asynchrone Datenbankfunktionen), werfen Sie einen Blick auf die [Async-Tests](../advanced/async-tests.md){.internal-link target=_blank} im Handbuch für fortgeschrittene Benutzer.

  8. docs/ko/docs/tutorial/request-files.md

    * `close()`: 파일을 닫습니다.
    
    상기 모든 메소드들이 `async` 메소드이기 때문에 “await”을 사용하여야 합니다.
    
    예를들어, `async` *경로 작동 함수*의 내부에서 다음과 같은 방식으로 내용을 가져올 수 있습니다:
    
    ```Python
    contents = await myfile.read()
    ```
    
    만약 일반적인 `def` *경로 작동 함수*의 내부라면, 다음과 같이 `UploadFile.file` 에 직접 접근할 수 있습니다:
    
    ```Python
    contents = myfile.file.read()
    ```
    
    !!! note  "`async` 기술적 세부사항"
        `async` 메소드들을 사용할 때 **FastAPI**는 스레드풀에서 파일 메소드들을 실행하고 그들을 기다립니다.

  9. docs/zh/docs/tutorial/testing.md

    ```
    
    !!! tip "提示"
        注意测试函数是普通的 `def`,不是 `async def`。
    
        还有client的调用也是普通的调用,不是用 `await`。
    
        这让你可以直接使用 `pytest` 而不会遇到麻烦。
    
    !!! note "技术细节"
        你也可以用 `from starlette.testclient import TestClient`。
    
        **FastAPI** 提供了和 `starlette.testclient` 一样的 `fastapi.testclient`,只是为了方便开发者。但它直接来自Starlette。

  10. docs/zh/docs/advanced/events.md

    # 事件:启动 - 关闭
    
    **FastAPI** 支持定义在应用启动前,或应用关闭后执行的事件处理器(函数)。
    
    事件函数既可以声明为异步函数(`async def`),也可以声明为普通函数(`def`)。
    
    !!! warning "警告"
    
        **FastAPI** 只执行主应用中的事件处理器,不执行[子应用 - 挂载](sub-applications.md){.internal-link target=_blank}中的事件处理器。
    
    ## `startup` 事件
    
    使用 `startup` 事件声明 `app` 启动前运行的函数:
    
    ```Python hl_lines="8"
    {!../../../docs_src/events/tutorial001.py!}
    ```
    
    本例中,`startup` 事件处理器函数为项目数据库(只是**字典**)提供了一些初始值。
    
    **FastAPI** 支持多个事件处理器函数。
