Answer 1

UserProfile Class

To create a `UserProfile` class in Python with attributes such as username, email address, and number of followers, you can define the class as follows:

class UserProfile:
    def __init__(self, username, email, followers):
        self.username = username
        self.email = email
        self.followers = followers
    
    def subscribe(self, user):
        # Add logic to subscribe to another user
        pass
    
    def unsubscribe(self, user):
        # Add logic to unsubscribe from another user
        pass
    
    def display_profile(self):
        # Add logic to display user profile information
        pass

In this class, the `__init__` method is used to initialize the attributes of the `UserProfile` object. The `subscribe` and `unsubscribe` methods can be implemented to handle the logic for subscribing and unsubscribing from other users. The `display_profile` method can be implemented to display the user's profile information.

ShoppingCart Class

To create a `ShoppingCart` class in Python to simulate an online shopping cart, you can define the class as follows:

class ShoppingCart:
    def __init__(self):
        self.items = []
    
    def add_item(self, item):
        # Add logic to add an item to the shopping cart
        pass
    
    def remove_item(self, item):
        # Add logic to remove an item from the shopping cart
        pass
    
    def calculate_total_cost(self):
        # Add logic to calculate the total cost of the items in the shopping cart
        pass
    
    def display_contents(self):
        # Add logic to display the contents of the shopping cart
        pass

In this class, the `__init__` method is used to initialize the `items` attribute as an empty list. The `add_item` and `remove_item` methods can be implemented to handle the logic for adding and removing items from the shopping cart. The `calculate_total_cost` method can be implemented to calculate the total cost of the items in the shopping cart. The `display_contents` method can be implemented to display the contents of the shopping cart.

Please note that the code provided above only outlines the structure of the classes and does not include the actual implementation logic. You will need to add the necessary code inside each method to perform the desired actions.
