Isso significa que ele **sempre terá um valor**, só que às vezes o valor pode ser `None` (ou `null` em termos de JSON).

Isso quer dizer que, os clientes que usam sua API não precisam verificar se o valor existe ou não, eles podem **assumir que o campo sempre estará lá**, mas que em alguns casos terá o valor padrão de `None`.

`@lru_cache` modifies the function it decorates to return the same value that was returned the first time, instead of computing it again, executing the code of the function every time.

Mas você ainda precisa usar `Path` para o parâmetro de path `item_id`. E você não quer usar `Annotated` por algum motivo.

O Python vai reclamar se você colocar um valor com “padrão” antes de um valor que não tem “padrão”.

Mas você pode reordená-los e colocar primeiro o valor sem padrão (o parâmetro de consulta `q`).
