まだ表面的な部分に触れただけですが、もう全ての仕組みは分かっているはずです。

以下の行を変更してみてください:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...以下を:

```Python
        ... "item_name": item.name ...
```

...以下のように:

```Python
        ... "item_price": item.price ...
```

...そして、エディタが属性を自動補完し、そのタイプを知る方法を確認してください。:

Die Syntax `{"name", "description"}` erzeugt ein `set` mit diesen zwei Werten.

Äquivalent zu `set(["name", "description"])`.

#### `list`en statt `set`s verwenden
