I am not sure how to solve the regx twitter handle?

I think I have use the multiline flag and marked the end of the string. I am checking the string variable because the instruction didn't say anything different, but when I look at the string variable there are no twitter handles at the end of each line. What am I missing?

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}),\s
''', string, re.X)

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

You are very close. The error is caused by using a caret (^) at the beginning of the regex pattern. The caret anchors the pattern to the beginning of each line. Since you wish to ignore the user name at the beginning of the line, you can either remove the caret, or add extra regex characters to consume the user name between the beginning of the line and the email address.

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

twitters = re.search(r'@[\w\d]+.$',string, re.MULTILINE) #<-- removed caret (^)
