Return a list of all the email addresses in the string

What is wrong with my code? I don’t think it’s is a syntax error, so is the error in my set?

sets_email.py 
import re

def find_emails(str):
    return(re.findall(r'[-\w\d+.]@[-\w\d.]', str))
# 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']

The error message gives you a clue:

Bummer: Didn't get the right output. Got ['h@t', 'a@t', 'e@e'], expected ['kenneth@teamtreehouse.com', 'andrew+gotcha@teamtreehouse.com', 'exa.mple@example.co.uk'].

It shows you that what it got for each entry was a single character on either side of "@" symbol, which is how the expression is currently coded. But if you add the "+" symbol to your character classes they will capture one or more of that type of character, which will produce the correct result.
