ID`baz`のitemのようにデフォルト値と同じ値を持つデータの場合:

```Python hl_lines="3 5 6"
{
    "name": "Baz",
    "description": None,
    "price": 50.2,
    "tax": 10.5,
    "tags": []
}
```

FastAPIは十分に賢いので（実際には、Pydanticが十分に賢い）`description`や`tax`、`tags`はデフォルト値と同じ値を持っているにもかかわらず、明示的に設定されていることを理解しています。（デフォルトから取得するのではなく）

そのため、それらはJSONレスポンスに含まれることになります。

/// tip | 豆知識

デフォルト値は`None`だけでなく、なんでも良いことに注意してください。
