Python Regex: Email Groups - Code Challenge

I'm at a loss on how to change this so it will satisfy the requirements of the challenge to pick out the twitter handles correctly.... From my understanding, its correct, but I suppose that's not the case!

emails.py 
import re

string = '''Love, Kenneth, kenneth+challenge@teamtreehouse.com, 555-555-5555, @kennethlove
Chalkley, Andrew, andrew@teamtreehouse.co.uk, 555-555-5556, @chalkers
McFarland, Dave, dave.mcfarland@teamtreehouse.com, 555-555-5557, @davemcfarland
Kesten, Joy, joy@teamtreehouse.com, 555-555-5558, @joykesten'''

contacts = re.search(r'''(?P<email>[-\w\d.+]+@[-\w\d.]+),\s
                         (?P<phone>\(?\d{3}\)?-?\s?\d{3}-\d{4})?
                         ''',string, re.X|re.M)

twitters = re.search(r'''
                         (?P<twitter>@[\w\d]+)?$
                      ''',string, re.X|re.M)

Hi Trevor Currie , unlike part 1, this part of the challenge didn't ask you to group the pattern, so you don't have to do that, the only problem here is the ? before $ in your matching string, you shouldn't put it there. Get rid of that ? and you'll pass.

And you can simplify it a bit by removing some of the unnecessary stuffs from you RegEx.

twitters = re.search(r'''
                         (@[\w\d]+)$
                      ''',string, re.X|re.M)

Hope that helps.

I just didn't denote the beginning of the line. I think I was running into errors but I can't recall.
