title: requests.get returns <!doctype> instead <Response>
body: <p>I have an issue with requests.get().
  If I paste the URL manually into the code as here:</p>
  
  <pre><code>r = requests.get('https://berlin.kauperts.de/Strassen/Igelsteig-12557-Berlin.html')
  print(r)
  </code></pre>
  
  <p>I get: <code>&lt;Response [200]&gt;</code>. Which works quite fine.
  Instead if I try to ask for the requests out of a list of files as in:</p>
  
  <pre><code>indir = '/home/d/Desktop/civiv_hacking/Streetnames/dump/berlin.kauperts.de/Strassen'
  for root, dirs, filenames in os.walk(indir):
    for z in filenames:
       x = urlparse.urljoin('https://berlin.kauperts.de/Strassen/', z+'/'),
       [t[0] for t in x],
       print(t),
       for r in requests.get(t):              
          print(r),
  </code></pre>
  
  <p>I get: <code>https://berlin.kauperts.de/Strassen/Igelsteig-12557-Berlin/ &lt;!DOCTYPE html&gt;
  &lt;html lang="de" xml:lang="de" xmlns="http://www.w3.org/1999/xhtml"&gt;
  </code>
  How can I make requests.get() return <code>&lt;Response [200]&gt;</code> instead of just the doctype information?</p>
