Python Object-Oriented Python Advanced Objects Dream Vacation

Positional arguments and classmethod

Task: Below is a class called DreamVacation that holds a location and list of activities. Create a @classmethod called rome that will return a new DreamVacation instance with cls() with the following arguments: location = 'Rome' and activities list = ['visit the Colosseum', 'Eat gelato'].

Hint: The classmethod should take cls instead of self as an argument.

Question: I get the error that I'm missing two positional arguments, but as far as I know, I did provide them.

class DreamVacation:
    def __init__(self, location, activities):
        self.location = location
        self.activities = activities
    # insert your code here

    def rome(cls):
        vacation = cls().__init__(location = 'Rome', activities = ['visit the Colosseum', 'Eat gelato'])
        return vacation

The constructor is called automatically when you create an instance:

        vacation = cls(location = 'Rome', activities = ['visit the Colosseum', 'Eat gelato'])
# or just:
        vacation = cls('Rome', ['visit the Colosseum', 'Eat gelato'])
