В этом случае вызовы super
не требуют аргументов:
class Car(object):
def __init__(self):
print("You just created the car instance")
def drive(self):
print("Car started...")
def stop(self):
print("Car stopped")
class BMW(Car):
def __init__(self):
super().__init__()
print("You just created the BMW instance")
def drive(self):
super().drive()
print("You are driving a BMW, Enjoy...")
def headsup_display(self):
print("This is a unique feature")
class BMW320(BMW):
def __init__(self):
super().__init__()
print("You created BMW320 instance")
def drive(self):
super().drive()
print("You are enjoying BMW 320")
c = Car()
c.drive()
c.stop()
b = BMW()
b.drive()
b.stop()
b.headsup_display()
b320 = BMW320()
b320.drive()
