I am trying to find, do I follow someone or not. I realized that although it is written in official Tweepy document, I cannot use API.exists_friendship anymore. Therefore, I tried to use API.show_friendship(source_id/source_screen_name, target_id/target_screen_name) and as the document said it returns me friendship object. (<tweepy.models.Friendship object at 0x105cd0890>, <tweepy.models.Friendship object at 0x105cd0ed0>) 
When I write screen_names = [user.screen_name for user in connection.show_friendship(target_id=someone_id)] it returns my_username and username for someone_id.
Can anyone tell me how can I use it properly? or is there any other method that simply returns me True/False because I just want to know do I follow him/her or not.
i am using below code this works fine  ..
     if(api.show_friendship(source_screen_name='venky6amesh', target_screen_name='vag')):
            print("the user is not a friend of ")
            try:
                api.create_friendship(j)
                print('success')
            except tweepy.TweepError as e:
                print('error')
                print(e.message[0]['code']) 
            else:
                print("user is a friend of ",j)
