Grabbing headers from webpage with python

问题:

How can I use python 3 to get access to the HTTP Headers. Specifically, I am trying to recreate the headers you can gain access to through network in the developer tools in chrome.

>>> import pprint
>>> import urllib.request
>>> u = urllib.request.urlopen('http://www.python.org')
>>> pprint.pprint(dict(u.getheaders()))
