#! /usr/bin/env python

# how to unfollow everyone who isn't following you
# By Jamieson Becker (Public Domain/no copyright, do what you will)

# Easy instructions, even if you don't know Python
#
# 1.  Install pip (apt-get install python-pip) and then
#     pip install tweepy, which is the python twitter client
#
# 2.  create a new app in your account at dev.twitter.com
#     and then plug in your consumer and app keys below.
#     Trim all whitespace at beginning/end of your keys.
#
# 3.  the twitter app needs to have permissions changed to
#     read-write, as apps are read-only by default.
# 
# 4.  Execute this script: python unfollow.py

import time
import tweepy
import sys

auth = tweepy.auth.OAuthHandler(
        consumer_key='foo',
        consumer_secret='bar')
auth.set_access_token(
        'foobaz',
        'foobar')

api=tweepy.API(auth_handler=auth)

print "Loading followers.."
follower_objects = [follower for follower in tweepy.Cursor(api.followers).items()]

print "Found %s followers, finding friends.." % len(followers)
friend_objects = [friend for friend in tweepy.Cursor(api.friends).items()]

# create dictionaries based on id's for easy lookup
friends = dict([(friend.id, friend) for friend in friend_objects])
followers = dict([(follower.id, follower) for follower in follower_objects])

# find all your "non_friends" - people who don't follow you even though you follow them.
non_friends = [friend for friend in friend_objects if friend.id not in followers]

# double check, since this could be a rather traumatic operation.
print "Unfollowing %s non-following users.." % len(non_friends)
print "This will take approximately %s minutes." % (len(non_friends)/60.0)
answer = raw_input("Are you sure? [Y/n]").lower()
if answer and answer[0] != "y":
    sys.exit(1)

# start the removal process. In the event of a failure (thanks, twitter!),
# retry once after five seconds. An error on same record again is
# probably more serious issue, so abort with error

for nf in non_friends:
    print "Unfollowing " + str(nf.id).rjust(10)
    try:
        nf.unfollow()
    except:
        print "  .. failed, sleeping for 5 seconds and then trying again."
        time.sleep(5)
        nf.unfollow()
    print " .. completed, sleeping for 1 second."
    time.sleep(1)

You are trying to echo followers on line 36, but it is not defined prior to that. Also, has anyone had any successes in making this thing work, it's not working

A simple script to easily Follow | Unfollow Twitter Followers | Unfollowers at once works like a charm.
