Since you're escaping the $ it will try to match the character as is, rather than use it's special meaning for being the end of a string. The comma also won't match since the Twitter handle is the last thing on the line and the re.MULTILINE flag is being used.

The rest of your regex is fine, though you might need to add the re.VERBOSE flag with the use of the docstring.

I have removed the escape hatchet on the $ and added the re.VERBOSE flag..It's now saying task1 no longer passing:(twitters = re.search(r''' (?P<twitter>[@\w\d]+) $ ''',string,re.VERBOSE,re.MULTILINE)

To combine flags you use the | operator. re.MULTILINE | re.VERBOSE for example. You'll end up with something like this:

twitters = re.search(r'''
    (?P<twitter>[@\w\d]+)$
   ''', string,re.MULTILINE | re.VERBOSE)

Oh I had forgot about the "|" operator, I should go and revise on that...thanks a lot Mr Dan:)
