## `Union` 或 `anyOf` { #union-or-anyof }

响应可以声明为两个或多个类型的 `Union`，即该响应可以是这些类型中的任意一种。

在 OpenAPI 中会用 `anyOf` 表示。

为此，请使用 Python 标准类型提示 [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union)：

/// note | 注意

定义 [`Union`](https://docs.pydantic.dev/latest/concepts/types/#unions) 类型时，要把更具体的类型写在前面，然后是不太具体的类型。下例中，更具体的 `PlaneItem` 位于 `Union[PlaneItem, CarItem]` 中的 `CarItem` 之前。

You also must install Python version 3.8 or later for the lambda handlers to work.
