When you declare a *path operation function* with normal `def` instead of `async def`, it is run in an external threadpool that is then awaited, instead of being called directly (as it would block the server).

1. これは最初のステージで、`requirements-stage`と名付けられます
2. `/tmp` を現在の作業ディレクトリに設定します
    ここで `requirements.txt` というファイルを生成します。

3. このDockerステージにPoetryをインストールします

4. pyproject.toml`と`poetry.lock`ファイルを`/tmp` ディレクトリにコピーします

    `./poetry.lock*`（末尾に`*`）を使用するため、そのファイルがまだ利用できない場合でもクラッシュすることはないです。
5. requirements.txt`ファイルを生成します

6. これは最後のステージであり、ここにあるものはすべて最終的なコンテナ・イメージに保存されます
7. 現在の作業ディレクトリを `/code` に設定します

`uv`는 다양한 기능을 지원합니다:

* 다양한 버전의 **Python 설치**
* 각 프로젝트 별 **가상 환경 관리**
* **패키지 설치**
* 프로젝트의 **의존성과 버전** 관리
* 설치된 패키지들과 그 버전을 **정확히 고정(lock)**해서,개발 환경과 운영 환경이 완전히 동일하게 작동할 수 있도록 보장
* 이 외에도 다양한 기능을 지원

## 결론

여기까지 모두 읽고 이해했다면, 이제 많은 개발자들보다 가상 환경을 **훨씬 더 깊이 있게 이해**하게 되셨습니다. 🤓
