現在我們建立一個相依，回傳新的 `config.Settings()`。

{* ../../docs_src/settings/app02_an_py310/main.py hl[6,12:13] *}

/// tip

我們稍後會討論 `@lru_cache`。

現在你可以先把 `get_settings()` 視為一般函式。

///

接著我們可以在*路徑操作函式 (path operation function)* 中將它宣告為相依，並在需要的地方使用它。

{* ../../docs_src/settings/app02_an_py310/main.py hl[17,19:21] *}

### 設定與測試 { #settings-and-testing }

接著，在測試時要提供不同的設定物件會非常容易，只要為 `get_settings` 建立相依覆寫（dependency override）即可：

    checkNotNull(function);
    return new FlatMapSpliteratorOfDouble<>(
        null, fromSpliterator, function, topCharacteristics, topSize);
  }

  /**
   * Implements the {@link Stream#flatMap} operation on spliterators.
   *
   * @param <InElementT> the element type of the input spliterator
   * @param <OutElementT> the element type of the output spliterators
   * @param <OutSpliteratorT> the type of the output spliterators
