of course ,that's just an example .
what I want to do is to get the direct url of a few URLs having redirections
,it would be better if this could be done asynchronously .
Currently ,I am using concurrent.futures.ThreadPoolExecutor , Requests ,and
QThread(for executing asynchronously ,not freeze the interface) to achieve it.

interface freezed?

It appears: concurrent.futures.as_completed yields futures as they complete, so
the main thread is blocked as it loops over this until all the futures have
completed.
You could use Qt's QNetworkAccessManager / QNetworkRequest, or perhaps you want
something like scrapy if you're trying to crawl websites (could probably be
integrated with a Qt app using qt4reactor)
What are you building?
