Practice with Classes: Barbie's Dreamhouse!

Barbie has graciously allowed us to work our Python magic on her Dreamhouse. Since Barbie loves to throw fabulous parties, she wants a Dreamhouse that can handle everything from the guest list to adding entire new rooms. Barbie insists on everything being picture-perfect!

Unfortunately for her, the rating of her Dreamhouse, and thus the success of her party, is dependent on a cleanliness score, which is constantly at risk thanks to guests who decide on a whim whether they want to behave.

In this exercise, you will implement this Dreamhouse class, and hope for the best for our friend Barbie!

Specifications

Here are the requirements Barbie has outlined for the Dreamhouse:

Implement your Dreamhouse as a class, with the following private data members:

__owner: The owner of the Dreamhouse (default is "Barbie").
__roomCount: The number of rooms in the Dreamhouse (initialized to 0).
__blocked: The name of the person currently blocked from entering (initialized to None).
__partySize: The number of people at the party (initialized to 0).
__roomOne and __roomTwo: The names of the rooms in the Dreamhouse (initialized to None)
__cleanliness: The cleanliness of the Dreamhouse (a random number between 0 and 100).

We need the following methods in the Dreamhouse:

__init__( x, owner = 'Barbie' ): the initializer for the class.
__str__(self): A method that returns a string representation of the Dreamhouse, including the owner's name, rating, party size, room names, and cleanliness.
The rating is out of five stars, calculated from the following formula:

(self.__cleanliness / 100) * 3 + self.__roomCount

This is to say: the cleanliness score contributes up to three full stars. Each room added to the Dreamhouse will grant one full star.
enter(self, name): A method that allows a guest to enter the Dreamhouse. If the person is blocked, print a warning. Otherwise, increase the party size.
evict(self, name): A method that evicts a guest from the Dreamhouse. It decreases the party size and adjusts the cleanliness based on how clean or messy the guest was.
getCleanliness(self): A getter method that returns the current cleanliness score of the Dreamhouse.
getOwner(self): A getter method that returns the name of the owner of the Dreamhouse.
setOwner(self, newOwner): A setter method that allows changing the owner of the Dreamhouse (default to "Barbie").
setBlock(self, newBlock): A setter method that allows specifying a person to block from entering the Dreamhouse.
addRoom(self, roomName): method that adds a room to the Dreamhouse. It increases the room count and assigns a room name if space is available.
crashParty(self, numKen): A method that summons Kens to crash the party. It enters and evicts the Kens repeatedly.

Template:

Barbie, the good samaritan she is, gave us the template for the Dreamhouse class. We simply need to fill in the bodies of the methods!

        two room slots.

        rating by 1 star.

        pass

    def crashParty(self, numKen):
