이렇게 하면 거의 전역 변수처럼 동작합니다. 하지만 의존성 함수를 사용하므로 테스트를 위해 쉽게 override할 수 있습니다.

`@lru_cache`는 Python 표준 라이브러리의 `functools`에 포함되어 있으며, 자세한 내용은 [`@lru_cache`에 대한 Python 문서](https://docs.python.org/3/library/functools.html#functools.lru_cache)에서 확인할 수 있습니다.

## 정리 { #recap }

Pydantic Settings를 사용하면 Pydantic 모델의 모든 강력한 기능을 활용해 애플리케이션의 설정 또는 구성을 처리할 수 있습니다.

* 의존성을 사용하면 테스트를 단순화할 수 있습니다.
* `.env` 파일을 사용할 수 있습니다.

如此一來，它的行為幾乎就像全域變數。但因為它使用相依函式，因此我們可以在測試時輕鬆將其覆寫。

`@lru_cache` 是 `functools` 的一部分，而 `functools` 是 Python 標準程式庫的一部分。你可以在[Python 文件中閱讀 `@lru_cache`](https://docs.python.org/3/library/functools.html#functools.lru_cache) 以了解更多。

## 回顧 { #recap }

你可以使用 Pydantic Settings 來處理應用程式的設定或組態，並享有 Pydantic model 的全部能力。

- 透過相依可以讓測試更容易。
- 你可以搭配 `.env` 檔使用。
