Why does it say "Said-variable" doesn't seem to be a regex object?
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<last_name>[+\w ]*), (?P<first_name>[+\w ]*), (?P<score>[\d]{2})''',string, re.M)

8,479 PointsRegex just takes practice. The more you do it, the more you understand what characters are used for and therefore where they should go. It's one of the harder concepts to pick up straight away.
There is a good cheat sheet on the web that abbreviates every regex character. In your code, you've not allowed for the commas and the colon after the name parts etc. You also missed the re.X and a couple of other letter bits. On the whole you weren't far off at all. :)
players = re.search(r'''
^(?P<last_name>[-\w\s]+),\s
(?P<first_name>[-\w\s]+):\s
(?P<score>[\d]+)$
''', string, re.X|re.M)

231,268 PointsThe error message might be misleading, perhaps the real issue is that the pattern isn't working on the data.
Take a close look at the entries and notice what separates the last names from the scores (Hint: it's not a comma). But you don't need the re.X since you're not spreading your pattern over separate lines like Andy did.
