そして当然、あるパラメータを必須に、別のパラメータにデフォルト値を設定し、また別のパラメータをオプショナルにできます:

{* ../../docs_src/query_params/tutorial006.py hl[10] *}

この場合、3つのクエリパラメータがあります。:

* `needy`、必須の `str` 。
* `skip`、デフォルト値を `0` とする `int` 。
* `limit`、オプショナルな `int` 。

[パスパラメータ](path-params.md#_8){.internal-link target=_blank}と同様に `Enum` を使用できます。
