Doesn't seem to compile for me in the task, but is ok when I run it in the python window on my pc.?

Here's the code I am running, seems to work ok, doesn't seem to work in the task?

import re string = '''Love, Kenneth: 20 Chalkley, Andrew: 25 McFarland, Dave: 10 Kesten, Joy: 22 Stewart Pinchback, Pinckney Benton: 18'''

players = re.search(r"(\w+),\s(\w+):\s(\d+)", string, re.MULTILINE)

players <_sre.SRE_Match object; span=(0, 17), match='Love, Kenneth: 20'>

players.py 
import re

string = '''Love, Kenneth: 20
Chalkley, Andrew: 25
McFarland, Dave: 10
Kesten, Joy: 22
Stewart Pinchback, Pinckney Benton: 18'''

players = re.search(r"(\w+),\s(\w+):\s(\d+)", string, re.MULTILINE)

You are on the right track. Add names to the groups in parens, Plus add spaces to the characters allowed for the first and last name:

players = re.search(r"(?P<last_name>[\w ]+),\s(?P<first_name>[\w ]+):\s(?P<score>\d+)", string, re.MULTILINE)

Error comes from two areas: un-handled edge case and unfulfilled challenge requirement.

  1. There seems to be an edge case for this line of data Stewart Pinchback, Pinckney Benton: 18 As you can see Stewart Pinchback does not follow the general convention of data format. I've tinkered a bit and figured out that challenge wants you to ignore not properly formatted data which is Stewart Pinchback (but not Pinckney Benton).

  2. Challenge asks you to capture them in a named group <last_name>, <first_name> and <score>. I tried without them and it failed as expected so you should include them in your pattern. I'm pretty sure you know how as you've made it this far.

If you are having trouble figuring the solution let me know, I'll post my passing code.

Thanks Guys, putting in the (tags/parens) seemed to do the trick ?P<last_name> etc...
