Can you get something like the following to work:

import urllib2

pword_manager = urllib2.HTTPPasswordMgrWithDefaultRealm()
pword_manager.add_password(None, 'http://localhost/
pwordProtectedStuff/', 'jane', 'janes_password')

authentication_handler = urllib2.HTTPBasicAuthHandler(pword_manager)
my_custom_urlopen_function =
urllib2.build_opener(authentication_handler)
urllib2.install_opener(my_custom_urlopen_function)

f = urllib2.urlopen('http://localhost/pwordProtectedStuff/test.htm')
print f.read()
