FastAPI построен поверх **Pydantic**, и я показывал вам, как использовать Pydantic-модели для объявления HTTP-запросов и HTTP-ответов.

Но FastAPI также поддерживает использование <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> тем же способом:

{* ../../docs_src/dataclasses_/tutorial001_py310.py hl[1,6:11,18:19] *}

{* ../../docs_src/middleware/tutorial001_py39.py hl[10,12:13] *}

/// tip | Примечание

Мы используем <a href="https://docs.python.org/3/library/time.html#time.perf_counter" class="external-link" target="_blank">`time.perf_counter()`</a> вместо `time.time()` для обеспечения большей точности наших примеров. 🤓

///

///

Параметр `status_code` приймає число, яке відповідає HTTP коду статусу.

/// info | Інформація
`status_code` також може отримувати значення з `IntEnum`, наприклад, з Python <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

Він буде:

* Повертати вказаний код статусу у відповіді.
