title: In Python, what does getresponse() return?
body: <pre><code> import httplib
      conn = httplib.HTTPConnection(head)
      conn.request("HEAD",tail)
      res = conn.getresponse()
  </code></pre>
  
  <p>I can get the <strong>res.status</strong> , which is the http status code.</p>
  
  <p>What other elements can I get?
  Why is it that when I do print <strong>res</strong>, it won't print the dictionary?  I just want to see the keys that are in that dictionary...</p>
