title: Python urlopen windows authentication
body: <p>I am not experienced with python and using the below code to open a url and read the response. I am getting an unauthorized error because the site uses Windows Authentication.  Can someone provide a code sample on how to send in the user name and password?</p>
  
  <pre><code>response = urllib.request.urlopen(url, params.encode("ASCII"))
  html = response.read()
  </code></pre>
