使用 `Query` 和 `Path`（以及你将在后面看到的其他类）可以声明字符串约束，但也可以声明数值约束。

像下面这样，添加 `ge=1` 后，`item_id` 将必须是一个大于（`g`reater than）或等于（`e`qual）`1` 的整数。

{* ../../docs_src/path_params_numeric_validations/tutorial004.py hl[8] *}

## 数值校验：大于和小于等于

同样的规则适用于：

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

{* ../../docs_src/path_params_numeric_validations/tutorial005.py hl[9] *}

## 数值校验：浮点数、大于和小于

数值校验同样适用于 `float` 值。
