Getting twitters for the Regular Expressions assignment

Could someone please explain the instructions in more detail? For finding all the Twitter accounts, I can use twitters = re.findall(r'\s@\w+', string), but the assignment wants me (us) to use re.search(). It seems I'm suppose to find a twitter account per name; is that suppose to be a function that takes a name? If not, what is this question asking?

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\d\-\.\+]*@[\d\w\-\.]+)
  ,\s
  (?P<phone>\(?\d{3}\)?\s?\-?\d{3}\-\d{4})
''', string, re.X)

twitters = re.search(r'\s@\w+$', string)

Your code should look something like this:

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'''

twitters = re.search(r'(?P<twitter>@[\w\d]+)$', string, re.M)

contacts = re.search(r"""
                    (?P<email>[-\w\d+.]+@[-\w\d.]+),\s
                    (?P<phone>\(?\d{3}\)?-?\s?\d{3}-\d{4})
""", string, re.X)

Thanks, but I don't think that's right. We're suppose to create a pattern that "catches the Twitter handle for a person," and our code "catches" it for the last Twitter or the first (without the $).

You're catching a space in your pattern, which you don't need, and you didn't use the re.MULTILINE flag.
