urllib2.URLError: <urlopen error (7, 'getaddrinfo failed')> when trying to connect through a proxy

I'm trying to get the HTML data off of a webpage.  Let's say for the
sake of argument it's the python homepage.  I've googled around and
found some examples that people said worked.  Here's what I've cobbled
together:

#getHTML.py
############################################
import urllib
import urllib2
proxy_info = {'user':'us3r',
              'password':'p at ssword',
              'host':'MY_PROXY',
              'port':'80'}
os.environ['HTTP_PROXY'] =
'http://%(user)s:%(password)s@%(host)s:%(port)s' % proxy_info
test_url = "http://www.python.org/index.html"
handle = urllib2.urlopen(test_url)
#handle = urllib.urlopen(test_url)
txt = handle.read().lower()
handle.close()
print "Text: "
print txt
#################################
#end getHTML.py

When I run this with urllib2 I get (with or without a dummy password):
Traceback (most recent call last):
  File "P:\My Documents\Projects\Python\validate_zipcodes.py", line
103, in ?
    handle = urllib2.urlopen(test_url)
  File "C:\Python23\lib\urllib2.py", line 129, in urlopen
    return _opener.open(url, data)
  File "C:\Python23\lib\urllib2.py", line 326, in open
    '_open', req)
  File "C:\Python23\lib\urllib2.py", line 306, in _call_chain
    result = func(*args)
  File "C:\Python23\lib\urllib2.py", line 901, in http_open
    return self.do_open(httplib.HTTP, req)
  File "C:\Python23\lib\urllib2.py", line 886, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error (7, 'getaddrinfo failed')>

When I run it with urllib.urlopen, I get:
Traceback (most recent call last):
  File "P:\My Documents\Projects\Python\validate_zipcodes.py", line
104, in ?
    handle = urllib.urlopen(test_url)
  File "C:\Python23\lib\urllib.py", line 76, in urlopen
    return opener.open(url)
  File "C:\Python23\lib\urllib.py", line 181, in open
    return getattr(self, name)(url)
  File "C:\Python23\lib\urllib.py", line 287, in open_http
    h = httplib.HTTP(host)
  File "C:\Python23\lib\httplib.py", line 1009, in __init__
    self._setup(self._connection_class(host, port, strict))
  File "C:\Python23\lib\httplib.py", line 507, in __init__
    self._set_hostport(host, port)
  File "C:\Python23\lib\httplib.py", line 518, in _set_hostport
    raise InvalidURL("nonnumeric port: '%s'" % host[i+1:])
httplib.InvalidURL: nonnumeric port: 'p at ssword@MY_PROXY:80'

Obviously, going through Internet Explorer works.

Has anyone else had a similar issue?  I don't know the proxy situation
we have here, so is it possible that the proxy is causing this?

Any help is much appreciated.

Thanks for at least reading this far!
