Can't import StreamListener

Question

I'm trying to create a data stream in Python using the Twitter API, but I'm unable to import the StreamListener correctly.

Here's my code:

import tweepy
from tweepy import Stream
from tweepy.streaming import StreamListener

class MyListener(StreamListener):
 
    def on_data(self, data):
        try:
            with open('python.json', 'a') as f:
                f.write(data)
                return True
        except BaseException as e:
            print("Error on_data: %s" % str(e))
        return True
 
    def on_error(self, status):
        print(status)
        return True
 
twitter_stream = Stream(auth, MyListener())
twitter_stream.filter(track=['#python'])

And I'm getting this error:

Traceback (most recent call last):
  File "c:\Users\User\Documents\GitHub\tempCodeRunnerFile.python", line 6, in <module>
    from tweepy.streaming import StreamListener
ImportError: cannot import name 'StreamListener' from 'tweepy.streaming' (C:\Users\User\AppData\Local\Programs\Python\Python39\lib\site-packages\tweepy\streaming.py)

Tweepy v4.0.0 was released yesterday and it merged StreamListener into Stream.

I recommend updating your code to subclass Stream instead.
Alternatively, you can downgrade to v3.10.0.

For Tweepy v4, you don't need to use StreamListener. The following is an edited code for v4:

import tweepy

class MyListener(tweepy.Stream):
    def on_data(self, data):
        try:
            with open('python.json', 'a') as f:
                f.write(data)
                return True
        except BaseException as e:
            print("Error on_data: %s" % str(e))
        return True
 
    def on_error(self, status):
        print(status)
        return True
 
twitter_stream = MyListener(
  "Consumer Key here", "Consumer Secret here",
  "Access Token here", "Access Token Secret here"
)
twitter_stream.filter(track=['#python'])

A slight tweak will fix this

#from tweepy.streaming import StreamListener #OLD CODE

import tweepy # NEW CODE

#class TweetListener (StreamListener): #OLD CODE

class TweetListener (tweepy.Stream): # NEW CODE
