为此，请使用 Python 标准类型提示 <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>：

/// note | 笔记

定义 <a href="https://docs.pydantic.dev/latest/concepts/types/#unions" class="external-link" target="_blank">`Union`</a> 类型时，要把详细的类型写在前面，然后是不太详细的类型。下例中，更详细的 `PlaneItem` 位于 `Union[PlaneItem，CarItem]` 中的 `CarItem` 之前。

## Typen und Validierung { #types-and-validation }

Якщо вам потрібне коротке нагадування про використання типів у Python (навіть якщо ви не використовуєте FastAPI), перегляньте короткий підручник: [Вступ до типів Python](python-types.md){.internal-link target=_blank}.

Ось приклад стандартного Python-коду з типами:

```Python
from datetime import date
from pydantic import BaseModel

# Оголошення змінної як str

```JSON
{"item_id":"foo"}
```

## Параметры пути с типами { #path-parameters-with-types }

Вы можете объявить тип параметра пути в функции, используя стандартные аннотации типов Python:

{* ../../docs_src/path_params/tutorial002_py39.py hl[7] *}

Здесь, `item_id` объявлен типом `int`.

         */
        BUILD_PROJECT,

 * <p>Path types are often exclusive. For example, a dependency should not be both on the Java class path
