**FastAPI**는 모두 Pydantic을 기반으로 되어 있습니다.

이 모든 것이 실제로 어떻게 사용되는지에 대해서는 [자습서 - 사용자 안내서](tutorial/index.md){.internal-link target=_blank} 에서 더 많이 확인하실 수 있습니다.

## **FastAPI**에서의 타입 힌트

**FastAPI**는 여러 부분에서 타입 힌트의 장점을 취하고 있습니다.

**FastAPI**에서 타입 힌트와 함께 매개변수를 선언하면 장점은:

* **에디터 도움**.
* **타입 확인**.

отличным вариантом (среди многих других) для разработки веб-API и приложений
в области дата-сайенс / машинного обучения.

Как добиться такого параллелизма в эксплуатации описано в разделе [Развёртывание](deployment/index.md){.internal-link target=_blank}.

## `async` и `await`

В современных версиях Python разработка асинхронного кода реализована очень интуитивно.
