Can't pass the challenge and not sure why

The last line of plays is giving me trouble and I am not sure how to tackle it

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'''
                   ^(?P<last_name>[\w]+),\s
                   (?P<first_name>[\w]+):\s
                   (?P<score>[\d]+*)$\s
                   '''
                    , string, re.X|re.M)

You're on the right track. A few items to correct

  • The "multiple repeat" error is due to the "+*". This says "zero or more of one or more" which the parser can't understand. Remove the asterisk.
  • The "Didn't find the correct information for Pinckney Benton Stewart Pinchback" error is due to missing the SPACE within the last and first names. Add a \s in both the last_name and first_name character sets.
  • Remove extraneous \s after the trailing $.

It should then pass the challenge. Good Luck!!!

Thanks for your reply!

The *+ was actually a typo. Should have just been +.

Now I did as you reccomended and the test passed. But I don't quiet understand why we needed a space in the first and last name character sets as I don't see any names (first or last) including a space in them.

I you may just clarify that, I'd understand this 100%. Thank you in advance :)

The space is need to capture the last name "Stewart Pinchback" and for the first name "Pinckney Benton"
