하지만 `Annotated`를 사용하고 있기에, `Annotated` 값을 변수에 저장하고 여러 장소에서 사용할 수 있습니다:

{* ../../docs_src/dependencies/tutorial001_02_an_py310.py hl[12,16,21] *}

/// tip | 팁

이는 그저 표준 파이썬이고 "type alias"라고 부르며 사실 **FastAPI**에 국한되는 것은 아닙니다.

하지만, `Annotated`를 포함하여, **FastAPI**가 파이썬 표준을 기반으로 하고 있기에, 이를 여러분의 코드 트릭으로 사용할 수 있습니다. 😎

## `Annotated` как тип для query-параметра `q`

Помните, как ранее я говорил об Annotated? Он может быть использован для добавления метаданных для ваших параметров в разделе [Введение в аннотации типов Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Пришло время использовать их в FastAPI. 🚀

У нас была аннотация следующего типа:

```Python
q: str | None = None
