My code produces the exact same output that team treehouse thinks it should produce, but it marks it wrong.

def find_emails(my_str): return re.findall(r'\w+.?\w*@\w+.\w+.?\w*', my_str)

sets_email.py 
import re

# Example:
# >>> find_email("kenneth.love@teamtreehouse.com, @support, ryan@teamtreehouse.com, test+case@example.co.uk")
# ['kenneth@teamtreehouse.com', 'ryan@teamtreehouse.com', 'test@example.co.uk']

def find_emails(my_str):
    return re.findall(r'\w+.?\w*@\w+.\w+.?\w*', my_str)

I agree the error message isn't helpful, and makes it look like the task should pass. I'd guess that perhaps the challenge does some other checking as well but used the wrong error message.

But ignoring the error message for a moment, the regex seems like it might allow things to be counted as email address that contain characters that should be disallowed.

You'll probably have better results if you avoid using the general wildcard (.) and rely more on character classes to screen the input.
