I have no clue...

I have no idea what I am doing wrong here. It just says twitters isn't a regex search object. Any help is appreciated.

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}-\d{3}-\d{4})
''', string, re.X|re.M)

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

Just one small correction makes a big difference (as is often the case with regex):

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

Notice that I removed the ^ from the beginning of your line. The ^ symbol matches against the beginning of a line, but the Twitter handles are not at the beginning of the lines in your string.

In this context the caret means match start of line. Confusingly it can also mean exclude in a slightly different context, such as:

[^0-9]

That would mean match anything that isn't a digit, for example.

Yes. I agree. The carrot symbol is a very confusing symbol.
