In that case, you can simply swap the standard `dataclasses` with `pydantic.dataclasses`, which is a drop-in replacement:

{* ../../docs_src/dataclasses_/tutorial003_py310.py hl[1,4,7:10,13:16,22:24,27] *}

1. We still import `field` from standard `dataclasses`.

2. `pydantic.dataclasses` is a drop-in replacement for `dataclasses`.

3. The `Author` dataclass includes a list of `Item` dataclasses.

Вы также можете использовать `from starlette import status` вместо `from fastapi import status`.

**FastAPI** позволяет использовать как `starlette.status`, так и `fastapi.status` исключительно для удобства разработчиков. Но поставляется fastapi.status непосредственно из Starlette.
