Running GET with SSL and authentication in Python

I can download things from my controlled server in one way - by passing the document ID into a link like so :

https://website/deployLink/442/document/download/$NUMBER

If I navigate to this in my browser, it downloads the file with ID $NUMBER.

The problem is, I have 9,000 files on my server, which is SSL encrypted and usually requires signing in with a username/password on a dialog box popup which appears on the web-page.

I posted a similar thread to this already, where I downloaded the files via WGET. Now I would like to try and use Python, and I'd like to provide the username/password and get through the SSL encryption.

Here is my attempt to grab one file, which results in a 401 error. Full stacktrace below.

import urllib2
import ctypes
from HTMLParser import HTMLParser

# create a password manager
password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()

# Add the username and password.
top_level_url = "https://website.com/home.html"
password_mgr.add_password(None, top_level_url, "admin", "password")
handler = urllib2.HTTPBasicAuthHandler(password_mgr)

# create "opener" (OpenerDirector instance)
opener = urllib2.build_opener(handler)

# Install the opener.
# Now all calls to urllib2.urlopen use our opener.
urllib2.install_opener(opener)

# Grab website
response = urllib2.urlopen('https://website/deployLink/442/document/download/1')
html = response.read()

class MyHTMLParser(HTMLParser):

url=''https://website/deployLink/442/document/download/1')'


# Save the file
webpage = urllib2.urlopen(url)
with open('Test.doc','wb') as localFile:
     localFile.write(webpage.read())

What have I done incorrectly here? Is what I am attempting possible?
