A python attribute between double underscores dunder, the .__base__ attribute let you reference the parent of a child class.

class Vehicle():
    can_fly = False
    number_of_weels = 0

class Car(Vehicle):
    number_of_weels = 4

    def __init__(self, color):
        self.color = color

my_car = Car("red")

print(my_car.__dict__['color'])
print(type(my_car).__dict__['number_of_weels'])
print(type(my_car).__base__.__dict__['can_fly'])
