Email groups pt1

I keep getting "Didn't get a regex search object." Why?

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

# name the email patter email and phone patter phone
# the comma spaces shouldn't be part of the groups

You're pretty close, but you forgot to account for the comma and space between the items.

Plus, in the spec for the phone number, you omitted the backslashes in front of the "d"s (so it is looking for literal "d" characters instead of digits).

Indeed, coding is like that! One other tip: since \w includes digits, you can replace the \d\w combinations with just \w.
