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。

abstract: TensorFlow is a machine learning system that operates at large scale and in heterogeneous environments. TensorFlow uses dataflow graphs to represent computation, shared state, and the operations that mutate that state. It maps the nodes of a dataflow graph across many machines in a cluster, and within a machine across multiple computational devices, including multicore CPUs, general purpose GPUs, and custom-designed ASICs known as Tensor Processing Units (TPUs).
