title: open url from pythonanywhere
body: <p>This code works well on my local machine, but when I upload and run it on pythonanywhere.com it gives me this error.
  <br>
  My Code:</p>
  
  <pre><code>url = "http://www.codeforces.com/api/contest.list?gym=false"
  hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',
                  'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                  'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
                  'Accept-Encoding': 'none',
                  'Accept-Language': 'en-US,en;q=0.8',
                  'Connection': 'keep-alive'}
           req = urllib2.Request(url, headers=hdr)
           opener = urllib2.build_opener()
           openedReq = opener.open(req, timeout=300)
  </code></pre>
  
  <p>The error:</p>
  
  <pre><code>Traceback (most recent call last):
  File "/home/GehadAbdallah/main.py", line 135, in openApi
