title: How to fix this AttributeError?
body: <p>I installed a stripe package yesterday and now my app is not running. I am trying to understand where the problem is. Is it something to do with <code>PyShell</code> or <code>HTLParser</code> or something else. I am posting with GAE tag as well hoping that the trace from logs may give a clue about the problem: </p>
  
  <pre><code>MLStripper instance has no attribute 'rawdata'
  Traceback (most recent call last):

  AttributeError: MLStripper instance has no attribute 'rawdata'
  </code></pre>
  
  <p>This is MLStripper:</p>
  
  <pre><code>from HTMLParser import HTMLParser
  
  class MLStripper(HTMLParser):
      def __init__(self):
          set()
          self.fed = []
      def handle_data(self, d):
          self.fed.append(d)
      def get_data(self):
          return ''.join(self.fed)
  
  def strip_tags(html):
      s = MLStripper()
      s.feed(html)
      return s.get_data()
  </code></pre>
  
  <p>MLStripper was working fine until yesterday.</p>
