I think that for twitters they want you to match the twitter handle for the whole regular expression, rather than in a captured group (in parentheses).

So, remove the part that matches everything before the @ sign:

twitters= re.search(r'(@[\w]+)$', string, re.MULTILINE)

And you could remove the parentheses/brackets too, since they aren't needed.

Thanks.
