Why do I keep getting: Bummer! error: bad character range }-\d at position 110 (line 3, column 20)

Is there something I am missing in the Regex I have here? I believe I'm doing it exactly as the video shows, what the heck

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  # email address comma and space not part of group
    (?P<phone>[\d{3}-\d{3}-\d{4}])  # phone number
''', string, re.X)

It looks like you have a little something extra that you probably did not intend.

:point_right: Brackets ([]) enclose a character class, but you don't need one here:

    (?P<phone>\d{3}-\d{3}-\d{4})  # phone number

Had the same problem and took the brackets out and was golden. Then changed it to a character class [-\d]+ and it worked as well. Cheers for the info!

Thank you. I thought the brackets are described in the video as being sets not ranges. The range of occurrences is in curly braces {3,5}.

Shouldn't a set like [\d]+ work for the score, just as well as \d\d or \d+
