In fact the following also works with Python 2.3.4:

import urllib2
proxy_handler = urllib2.ProxyHandler({"http": "http://john:blah@localhost:3128"})
print urllib2.build_opener(proxy_handler).open('http://python.org/').read()


...but only just barely skirts around the bugs!-)  :-(

(at least, the current bugs: I've no reason to work out what things
were like back in 2.3.4, but the above certainly works with that
version)
