  <p>It looks like both examples are failing when trying to query Digg.com. Here is the query that is constructed in ex3.py's code: </p>
  
  <pre><code>diggf = lambda r: {"title": r["title"]["value"], "diggs": int(r["diggCount"]["value"])}
  digg = db.select(name="dg", udf=diggf, url="http://digg.com/rss_search?search=google+android&amp;area=dig&amp;type=both&amp;section=news")
