Exercise 2: twitter handler

Hey there,

I am struggling a bit with this exercise. I successfully created a re.search for the email and number. I seem to have a problem with doing the same with twitter. Even though I get the twitter handler it tells me that it is the wrong output. Maybe I missunderstood the question. Could you please have a look

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("(?P<email>[\w\+]+@[\w\.]+), (?P<phone>[\d-]{12})", string)
twitters = re.search("\s@\w+", string, re.MULTILINE)

Your answer is very close. Two small issues though, the way you currently have it the regex does return the twitter handle but you may notice that there is a space in the front of the handle. ie: " @Kennethlove". To fix this just remove the "\s" from the front of the regex since you don't want to accept that space.

The second issue is from this part of the instructions "Remember to mark it as being at the end of the string." If you recall from the video we can use the '^' to mark the beginning of the string and a '$' to mark the end. So with all of this, the correct regex would be

twitters = re.search("@\w+$", string, re.MULTILINE)

Hi Michael,

That was indeed my mistake. Thank you very much for the quick answer.
