Didn't get the right groups from your regex

Hi Kenneth,

I went through the questions & answers in the forum, but didn't find anyone else having the same issue.

I ran this on my local IDE (Spyder) which produced the following results when print contacts, contacts.group(), contacts.groupdict() using the code:

contacts = <_sre.SRE_Match object; span=(15, 64), match='[email protected], 555-555-5555> contacts.group() = [email protected], 555-555-5555 contacts.groupdict() = {'email': '[email protected]', 'phone': '555-555-5555'}

because there is no example of the correct answer, I'm not sure what I missed.

It'd be great if you could help.

Many thanks,

emails.py 
import re

string = '''Love, Kenneth, [email protected], 555-555-5555, @kennethlove
Chalkley, Andrew, [email protected], 555-555-5556, @chalkers
McFarland, Dave, [email protected], 555-555-5557, @davemcfarland
Kesten, Joy, [email protected], 555-555-5558, @joykesten'''

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

I believe your issue is that you need to pass the re.M (Multiline) flag instead of the re.I (Ignore Case) flag. Since you're not matching any specific character cases in the regex, you don't need the Ignore Case flag.
