```

関数内のパラメータの値は以下の様になります:

* `skip=20`: URL内にセットしたため
* `limit=10`: デフォルト値

## オプショナルなパラメータ

同様に、デフォルト値を `None` とすることで、オプショナルなクエリパラメータを宣言できます:

{* ../../docs_src/query_params/tutorial002.py hl[9] *}

この場合、関数パラメータ `q` はオプショナルとなり、デフォルトでは `None` になります。

/// check | 確認

パスパラメータ `item_id` はパスパラメータであり、`q` はそれとは違ってクエリパラメータであると判別できるほど**FastAPI** が賢いということにも注意してください。

### Aviso sobre a substituição

Isso significa que, se você quiser atualizar o item `bar` usando `PUT` com um corpo contendo:

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

Como ele não inclui o atributo já armazenado `"tax": 20.2`, o modelo de entrada assumiria o valor padrão de `"tax": 10.5`.

E os dados seriam salvos com esse "novo" `tax` de `10.5`.
