Hi Rungano Matonda, the regular expression needs to match a complete email address. Your current regex r'\b[@]+{1}\b' says:

word-boundary start-set @-char end-set one-or-more-sets exactly-once word-boundary

What you need is:

word-boundary start-set legal-pre-@-chars end-set one-or-more sets AT-sign start-set legal-post-@-chars end-set one-or-more sets word-boundary

where legal-pre-@-chars is any-word-char, period, and plus-sign, and legal-post-@-chars is any-word-char, and period

This can be represented by the regex r'\b[\w.+]+@[\w.]+\b'

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

Thanks a lot Chris...That really helped me out:)
