not able to pass challenge 2-2

Hi all,

Here's my code.

I got two questions here. First, what \t really mean inside the statement ?

Second, I don't know why my re.search always return me None. I tried to seperate search for name and twitter, both works. But once it combines, it just doesn't work.

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

twitters = re.search(r'''
    ^(?P<name>[-\w]+,\s[-\w]+),\t
    (?P<twitter>@[\w\d]+),\t$
    ''', string, re.X|re.M)

It's been a while since I did regular expressions, but I think \t is the code for trailing whitespace. For the second part of your question, I think the way you are searching for name and twitter assumes that one directly follows the other in the string. Make sure to account for all the stuff that comes between the name and the twitter handle and regexp should be able to find both.
