cls() not recognized

Error is:

AssertionError: Regex didn't match: 'cls\(.+\)' not found in "class DreamVacation:\n def init(self, location, activities):\n self.location = location\n self.activities = activities\n # insert your code here\n @classmethod\n def rome(cls):\n inst = cls()\n inst.location = 'Rome'\n inst.activities = ['visit the Colosseum', 'Eat gelato']\n return inst" : Make sure to return a new instance using cls().

Code is below. Clearly cls() is there. why isn't it "found"?

class DreamVacation:
    def __init__(self, location, activities):
        self.location = location
        self.activities = activities
    # insert your code here
    def rome(cls):
        self = cls(location='Rome',
                   activities=['visit the Colosseum', 'Eat gelato']
        return self

The issue is the checker expects all of the parameters on the same line. While the code above is correct, for Task 1, the checker rejects it.

Developers: please change the regex to include the re.DOTALL flag (re.S) so that newlines can be "seen" between parens.

Marking as feedback.

Hey Chris Freeman I am not seeing any issue with the code you have here, but it looks like the challenge is wanting you to pass in just the arguments.

        return cls('Rome', ['visit the Colosseum', 'Eat gelato'])

This issue is the checker rejects my code above precisely because I split the arguments into multiple lines. I feel the regex is too restrictive and rejecting valid code.
