title: "AttributeError: module 'tweepy' has no attribute 'StreamListener'" with Python 3.9
body: <pre><code>class MyStreamListener(tweepy.StreamListener):
      def on_status(self, status):
          print(status.text)  # prints every tweet received
  
      def on_error(self, status_code):
          if status_code == 420:  # end of monthly limit rate (500k)
              return False
  </code></pre>
  <p>I use Python 3.9 and installed Tweepy via pip. I get the <code>AttributeError</code> on the class line.
  My import is just <code>import tweepy</code>. Authentication gets correctly handled.
  In the <code>streaming.py</code> file, I have the class <code>Stream</code>. But using this class ends in that. There is for example no <code>status.text</code>, even if there is the <code>on_status</code> function. I am a little bit confused.</p>
