Kiran install_opener() sau biyu ba ya ƙara opener na biyu ga na farko. Yana maye gurbin opener na tsoho na module ɗin. Idan abu ɗaya ya san proxy ɗin kuma wani ya san shiga gidan yanar gizo, gina opener ɗaya mai ɗauke da handlers ɗin da ake buƙata.

import os
from urllib.request import (ProxyHandler, HTTPBasicAuthHandler,
