I keep getting this error: 'API' object has no attribute 'followers'. Any idea what might be the problem? Is this code outdated?

The code is more than 3 years old. twitter API's have updated.
Checkout - https://docs.tweepy.org/en/stable/api.html for the latest API ref

That makes sense! Thank you for the comment.
