Help me, i did 50 try's :D

Create a new variable named contacts that is an re.search() where the pattern catches the email address and phone number from string. Name the email pattern email and the phone number pattern phone. The comma and spaces * should not* be part of the groups.

What i do wrong?

emails.py
import re

string = '''Love, Kenneth, kenneth+challenge@teamtreehouse.com, 555-555-5555, @kennethlove
Chalkley, Andrew, andrew@teamtreehouse.co.uk, 555-555-5556, @chalkers
McFarland, Dave, dave.mcfarland@teamtreehouse.com, 555-555-5557, @davemcfarland
Kesten, Joy, joy@teamtreehouse.com, 555-555-5558, @joykesten'''

contacts = re.search(r'''
    ^(?P<email>([\w.+]+)?@[\w\s.]+)\t
    (?P<phone>[\d]{3}-[\d]{3}-[\d]{4})$
''',string,re.I|re.M)

Here are the corrections needed:

  • remove caret (^) starting anchor since pattern doesn’t start at beginning of string
  • remove dollar sign ($) EOL anchor since pattern doesn’t end at End-of-line
  • use comma space (,\s) between patterns instead of tab (\t)
  • remove inner group defined by (...)? as in causes returned groups not to match expected groups
  • the space (\s) in the email domain name is unnecessary, but will pass task 1
  • change re.I to re.M for multi-line interpretation

Post back if you need more help. Good luck!!!
