?P<>

My code is returning empty. I think my problem is with ?P<>. Do I need to add something to put them both on one line?

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.findall(r'(?P<email>[\w+.]+@[\w.]+)(?P<phone>\d{3}-\d{3}-\d{4})',string)

Hi Elizabeth,

The challenge instructions say to use re.search so you'll need to switch to that instead of re.findall

The only other issue is that you're not matching the comma and space between the email and phone number. You have to match these but they shouldn't be part of your named groups.

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

I've tried it with both search and findall, and it return empty both ways. I will try adding the comma and space.

Yes, you have to switch to re.search but also add in the comma and space.

You have to put it between your 2 named groups as I've shown in the code above.

Thanks, the comma and the space worked. That makes sense. I thought it was pulling out any email and any phone number it found, but it makes sense that it is pulling out an email/phone combination.
