## 숫자 검증: 크거나 같음

`Query`와 `Path`(나중에 볼 다른 것들도)를 사용하여 문자열 뿐만 아니라 숫자의 제약을 선언할 수 있습니다.

여기서 `ge=1`인 경우, `item_id`는 `1`보다 "크거나(`g`reater) 같은(`e`qual)" 정수형 숫자여야 합니다.

## 숫자 검증: 크거나 같음 및 작거나 같음

동일하게 적용됩니다:

    description: Union[str, None] = None
    price: float
    tax: Union[float, None] = None


@app.put("/items/{item_id}")
async def update_item(
    item_id: Annotated[int, Path(title="The ID of the item to get", ge=0, le=1000)],
    q: Union[str, None] = None,
    item: Union[Item, None] = None,
):
    results = {"item_id": item_id}
    if q:
        results.update({"q": q})
    if item:
        results.update({"item": item})

## 数值校验：大于等于

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。

## 数值校验：大于和小于等于
