Por hora, você precisa apenas saber que o `Annotated` existe, e que ele é Python padrão. 😎

Mais tarde você verá o quão **poderoso** ele pode ser.

the key was too small, but at any rate it would not open any of
them.  However, on the second time round, she came upon a low
curtain she had not noticed before, and behind it was a little
door about fifteen inches high:  she tried the little golden key
in the lock, and to her great delight it fitted!

  Alice opened the door and found that it led into a small
passage, not much larger than a rat-hole:  she knelt down and

O parâmetro de consulta `q` é do tipo `Union[str, None]`, o que significa que é do tipo `str` mas que também pode ser `None`, e de fato, o valor padrão é `None`, então o FastAPI saberá que não é obrigatório.

/// note | Observação

O FastAPI saberá que o valor de `q` não é obrigatório por causa do valor padrão `= None`.

**FastAPI** tiene su propio `HTTPException`.

Y la clase de error `HTTPException` de **FastAPI** hereda de la clase de error `HTTPException` de Starlette.

La única diferencia es que el `HTTPException` de **FastAPI** acepta cualquier dato JSON-able para el campo `detail`, mientras que el `HTTPException` de Starlette solo acepta strings para ello.

Así que puedes seguir lanzando un `HTTPException` de **FastAPI** como de costumbre en tu código.
