Why doesn't this produce anything???

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

Kesten, Joy, joy@teamtreehouse.com, 555-555-5558, @joykesten'''

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

At first glance, three issues stand out.

  • the "^" and "$" anchor the patterns to the beginning and end of the string, but that's not where they are
  • the comma in between is not accounted for
  • the \t only matches a tab, use \s instead to match any spacing character
