APIs are almost the same

Python 2.7
>>> import httplib
>>> conn = httplib.HTTPConnection("2ch.so")
>>> conn.request("GET", "/menu.html")
>>> r = conn.getresponse()
>>> r.read().split('\n')
>>> conn.close()

Python 3.2
>>> from http import client
>>> conn = client.HTTPConnection(r'2ch.so')
>>> conn.request('GET', '/menu.html')
>>> r = conn.getresponse()
>>> r.readlines()
>>> conn.close()
