# yieldを持つ依存関係

FastAPIは、いくつかの<abbr title='時々"exit"、"cleanup"、"teardown"、"close"、"context managers"、 ...のように呼ばれる'>終了後の追加のステップ</abbr>を行う依存関係をサポートしています。

これを行うには、`return`の代わりに`yield`を使い、その後に追加のステップを書きます。

/// tip | 豆知識

`yield`は必ず一度だけ使用するようにしてください。

これを動作させるには、**Python 3.7** 以上を使用するか、**Python 3.6** では"backports"をインストールする必要があります:

```
pip install async-exit-stack async-generator
```

### Mehrere Prozesse – Ein Beispiel

Im folgenden Beispiel gibt es einen **Manager-Prozess**, welcher zwei **Workerprozesse** startet und steuert.

Dieser Manager-Prozess wäre wahrscheinlich derjenige, welcher der IP am **Port** lauscht. Und er würde die gesamte Kommunikation an die Workerprozesse weiterleiten.
