Regular expressions and groups

I'm getting the error "unterminated character set at position 100 (line 3, column 45)". I'm not entirely sure what that means, nor what's wrong with my code. Any help would be greatly 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)

At the end of your expression, you have a digit repeated 4 times coded like this: "\d[4}" (with a square bracket) instead of "\d{4}" (with a brace).

The bracket is being interpreted as the beginning of a character set definition that is never completed.

Ahh, I was looking at that for so long trying to figure it out. Thanks a ton, man!
