Esse código declara um parâmetro de consulta opcional, `q`, com o tipo `str`, e então retorna esse parâmetro.

Isso é bastante simples (e não muito útil), mas irá nos ajudar a focar em como as subdependências funcionam.

## Segunda dependência, "dependable" e "dependente" { #second-dependency-dependable-and-dependant }

Python exception’ı olduğu için `return` etmezsiniz, `raise` edersiniz.

Bu aynı zamanda şunu da ifade eder: *path operation function*’ınızın içinde çağırdığınız bir yardımcı (utility) fonksiyonun içindeyken `HTTPException` raise ederseniz, *path operation function* içindeki kodun geri kalanı çalışmaz; request’i hemen sonlandırır ve `HTTPException` içindeki HTTP hatasını client’a gönderir.
