Create a variable named players that is an re.search() or re.match() to capture three groups: last_name, first_name, and score. It should include re.MULTILINE.
I get this error:
Bummer: error: nothing to repeat at position 73 (line 4, column 14)
import re
string = '''Love, Kenneth: 20
Chalkley, Andrew: 25
McFarland, Dave: 10
Kesten, Joy: 22
Stewart Pinchback, Pinckney Benton: 18'''
players = re.search(r'''
^(?P<first_name>[-\w]*),\s
(?P<last_name>[-\w]*)?:\s
(?P<score>?\d{2})$
''', string, re.X|re.M)
not sure what to do from here...

Treehouse Moderator 68,425 PointsHey diginoma, Often the error message has all the info you need. The 73rd character of your regex is the ? following <score>. This means "one or none" of something. But there isn't anything between the field name and the ?. Hence the error. Remove this ?, and you're on your way....
The code will run but return a wrong value. Hint: are you capturing spaces that might be within the first or last names?
Your re flags are correct.
- re.X is for verbose code making all whitespace explicitly encoded in the regex (regular whitespace is ignored).
- re.M is for multiline, in that, you wish to run the regex pattern on each line (up to the newline char) within the multi-line input string.
Post back if you need more help. Good luck!!
