Groups coding exercise

Hey, I'm having problems getting this to work in the workspace. It runs fine in an external python session but in workspace am getting an error:

no .groups() attribute

Could anyone please help? What is groups an attribute of?

Thanks, Matt

names.py
import re

string = 'Perotto, Pier Giorgio'

names =re.findall(r'''
    (^[\w]*),\s
    ([-\w]*\s?[-\w]*)
''', string, re.X)

The issue is that you are using re.findall instead of what the task asks for, re.match. The code you provide runs fine even in workspaces. Just change to re.match for the task and it passes!
