Python Regular Expressions in Python Introduction to Regular Expressions Players Dictionary and Class

Why is 'player' not recognized as 'regex' object?

Code challenge for Compiling and Loops; code -

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   # Last Names
    (?P<first_name>[-\w]+):\s   # First Names
    (?P<score>[\d]+)   # Score
''', string, re.X|re.M).group()   # VERBOSE and MULTILINE
  • works in WorkSpace but gets " 'players` doesn't seem to be a regex object." in challenge. I'm probably missing some nuance they are looking for in this case.?

This one really stumped me for a while. And then I just got it. was getting the same 'player doesn't seem to be a reggae object' comment. 

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

You aren't allowing a person to have multiple words in each name, like our last player Pinckney Benton.

Yep, that's it. I'm not allowing for a person to have multiple words in each name, like last player Pinckney Benton. (ooooh, theys tricksey, my precious ...) Thx!

When you .group() the search object, you're going to get a string back. So type(players) is a string

Without the .group() method, you get a search object back. Is that what is being asked for in the challenge?

gavin, Thx! for resp, appreciate the thot. Trying w/o 'group, groups, or groupdict' gets "Bummer! Didn't get the right results. Got [('Love', 'Kenneth', '20'), ('Chalkley', 'Andrew', '25'), ('McFarland', 'Dave', '10'), ('Kesten', 'Joy', '22')]." The instruction is: 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.

So once you remove group, you're getting back all of the lines except for the last one.

How are you dealing with the last line, which looks like a pair of people with one score?

Or maybe the person is really named Pinckney Benton Stewart Pinchback.

Are you dealing with the fact that a first name and a last name can include whitespace?

edit: Knew of Robert Smalls, Frederick Douglass, etc. PBS Pinchback? How could he not come up, if not just to invoke the name?
