twitter data with python

Hello. I want to mine twitter data using python. I started by making an initial example, but it is giving error.

I imported twitter_python into the python 3.6 lib folder through the setupe.py install command at the windows prompt. The code:

import twitter  
api=twitter.Api()  

statuses=api.GetPublicTimeline()  

print(s.user.name for s in statuses)  

Follow the error link

follow the folder site package:
