これは以下のようなことが必要な時にとても便利です:

* ロジックを共有している。（同じコードロジックを何度も繰り返している）。
* データベース接続を共有する。
* セキュリティ、認証、ロール要件などを強制する。
* そのほかにも多くのこと...

これらすべてを、コードの繰り返しを最小限に抑えながら行います。

## 最初のステップ { #first-steps }

非常にシンプルな例を見てみましょう。あまりにもシンプルなので、今のところはあまり参考にならないでしょう。

しかし、この方法では **Dependency Injection** システムがどのように機能するかに焦点を当てることができます。

### 依存関係（「dependable」）の作成 { #create-a-dependency-or-dependable }

まずは依存関係に注目してみましょう。

        # self._type_adapter.validate_python(value)
        # This uses Pydantic's dump_json() which serializes directly to JSON
        # bytes in one pass (via Rust), avoiding the intermediate Python dict
        # step of dump_python(mode="json") + json.dumps().
        return self._type_adapter.dump_json(
            value,

  # Find all one-step dependencies of those tests which are from //tensorflow
  # (since external deps will come from Python-level pip dependencies),
  # excluding dependencies and files that are known to be unneccessary.
