Regular Expressions

Hey, I've been assigned to find certain emails from a string. Which part of my code is causing the error?

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(string):
    cr7 = re.findall(r'\b[\w,\d,.,+]+\b@[\d,.]+,[\w,.]+',string)
    return cr7

Inside the brackets, the . that normally matches everything matches only a literal '.' So after your @, you're requiring one or more digits or .'s. Try to simplify your regex so that it's easier to understand. For example, \w already matches digits, so you don't need to include \d inside the brackets. Something like https://regex101.com/ can help you get a feel for how things match.
