2つ目のバージョンは「絶対インポート」です:

```Python
from app.routers import items, users
```

Python のパッケージとモジュールについて詳しくは、[公式の Python モジュールに関するドキュメント](https://docs.python.org/3/tutorial/modules.html)をご覧ください。

///

### 名前衝突の回避 { #avoid-name-collisions }

サブモジュール `items` の変数 `router` だけをインポートするのではなく、サブモジュール自体を直接インポートしています。

これは、サブモジュール `users` にも `router` という変数があるためです。

もし次のように続けてインポートした場合:

### 自分で async コードを書く { #write-your-own-async-code }

Starlette (**FastAPI** も) は [AnyIO](https://anyio.readthedocs.io/en/stable/) の上に構築されており、標準ライブラリの [asyncio](https://docs.python.org/3/library/asyncio-task.html) と [Trio](https://trio.readthedocs.io/en/stable/) の両方に対応しています。

特に、あなた自身のコード内で、より高度なパターンを必要とする発展的な並行処理のユースケースに対して、[AnyIO](https://anyio.readthedocs.io/en/stable/) を直接使えます。

 * assigned characters, including important CJK characters and emoji.

### 여러분만의 async 코드 작성하기 { #write-your-own-async-code }

Starlette(그리고 **FastAPI**)는 [AnyIO](https://anyio.readthedocs.io/en/stable/)를 기반으로 하고 있으며, 파이썬 표준 라이브러리 [asyncio](https://docs.python.org/3/library/asyncio-task.html)와 [Trio](https://trio.readthedocs.io/en/stable/) 모두와 호환됩니다.

특히, 코드에서 더 고급 패턴이 필요한 고급 동시성 사용 사례에서는 직접 [AnyIO](https://anyio.readthedocs.io/en/stable/)를 사용할 수 있습니다.
