Redirection url using urllib in Python 3

I would ne开发者_如何转开发ed to know what is my final URL when following redirections using urllib in Python 3.

Let's say I've some code like :

opener = urllib.request.build_opener()
request = urllib.request.Request(url)
u = opener.open(request)

If my urls redirects to another website, how can I know this new website URL ? I've found nothing useful in documentation.

Thanks for your help !

You can simply use

u.geturl()

to get the URL you were redirected to (or the original one if no redirect happened).
