Why am I getting a regex search error?

It keeps saying that it’s not getting the “regex search object” but I can’t really find wha the problem is. I have looked at other questions by other treehouse students, but when I try what works for them, it gives me the error.

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.M)

This pattern is in the verbose style, but the re.X flag needed to indicate that is missing from the flags argument.

Also, the syntax for creating named groups requires a question mark between the open parenthesis and the "P" — for example: (?P<name>...).
