而且你还可以声明数值校验：

* `gt`：大于（`g`reater `t`han）
* `ge`：大于等于（`g`reater than or `e`qual）
* `lt`：小于（`l`ess `t`han）
* `le`：小于等于（`l`ess than or `e`qual）

!!! info
    `Query`、`Path` 以及你后面会看到的其他类继承自一个共同的 `Param` 类（不需要直接使用它）。

    而且它们都共享相同的所有你已看到并用于添加额外校验和元数据的参数。

!!! note "技术细节"
    当你从 `fastapi` 导入 `Query`、`Path` 和其他同类对象时，它们实际上是函数。

    当被调用时，它们返回同名类的实例。

    如此，你导入 `Query` 这个函数。当你调用它时，它将返回一个同样命名为 `Query` 的类的实例。
