Tweepy's **Stream Listener** passes error codes to an **on_error** stub. The
default implementation returns **False** for all codes, but we can override it
to allow Tweepy to reconnect for some or all codes, using the backoff
strategies recommended in the `Twitter Streaming API Connecting
Documentation`_. ::
class MyStreamListener(tweepy.StreamListener):
def on_error(self, status_code):
if status_code == 420:
#returning False in on_data disconnects the stream
#returning False in on_error disconnects the stream
return False
