Just functions that look the same as the *path operation functions*.

Pero FastAPI también soporta el uso de [`dataclasses`](https://docs.python.org/3/library/dataclasses.html) de la misma manera:

Esto sigue siendo soportado gracias a **Pydantic**, ya que tiene [soporte interno para `dataclasses`](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel).
