I tried to execute the following code to get the timeline from twitter in python,
It didn't work.
I wondered if I couldn't create the class that inherits StreamListener because the Listener isn't defined, but I'm not quite sure about StreamListener. Is the syntax wrong? Or is there something I should do before writing the syntax?
Could you tell me the cause of the error and the StreamListener?

class Listener(tweepy.StreamListener):
    def on_status(self, status):
        status.created_at += timedelta(hours=9)
        print('------------------------------')
        print(status.text)
        print("{name}({screen}) {created} via {src}\n".format(name=status.author.name, screen=status.author.screen_name,created=status.created_at, src=status. source))

listener = Listener()
stream = tweepy.Stream(auth, listener)
stream.filter(track = ["programming"])
