We can use multiple inheritance to add this new class as a parent of our existing Friend class. The tricky part is that we now have two parent __init__ methods, both of which need to be initialized. And they need to be initialized with different arguments. How do we do this? Well, we could start with a naive approach:
class Friend(Contact, AddressHolder):
def __init__(
self, name, email, phone, street, city, state, code):
Contact.__init__(self, name, email)
AddressHolder.__init__(self, street, city, state, code)
self.phone = phone
In this example, we directly call the __init__ function on each of the superclasses and explicitly pass the self argument. This example technically works; we can access the different variables ...
