title: urllib2.HTTPError: HTTP Error 503: Service Unavailable error while using python google search
body: <p>I'm using python google search to get the top 3 links for a query.
  The following is the code. My list contains 1000 queries and I'm trying to save them into a dictionary with the query as the key and URLs as the value.</p>
  
  <pre><code>from google import search
  for each in list:
      time.sleep(1)
      for URL in search(each,stop=3,num=3):
          print URL
  </code></pre>
  
  <p>When I try to execute this, I get the error: </p>
  
  <blockquote>
    <p>urllib2.HTTPError: HTTP Error 503: Service Unavailable</p>
  </blockquote>
  
  <p>Should I use requests or any other libraries to eliminate this error?</p>
