Now create a Car subclass and Truck subclass for Vehicle parent class.

Constructor

arguments:

wheels, miles, make, model, year, sold_on , base_sale_price

State change:

A new object is created.

Return:

That newly created object.

Implementation:

s = Truck(6, 10000, 'MTVR', '2500', 2014,12/12/12,15000)

t = Truck(6, 10000, 'MTVR', '2500', 2014,None,15000)

u = Car(4, 10000, 'Honda', 'Accord', 2014,None,10000)

v = Car(4, 10000, 'Honda', 'Accord', 2014,10/12/12,10000)

print ("Purchase price of Truck is ",s.purchase_price())

print ("Sale price of Truck is ",s.sale_price())

print ("Purchase price of Truck is ",t.purchase_price())

print ("Sale price of Truck is ",t.sale_price())

print ("Purchase price of Car is ",u.purchase_price())

print ("Sale price of Car is ",u.sale_price())

print ("Purchase price of Truck is ",v.purchase_price())

print ("Sale price of Truck is ",v.sale_price())

Now create an abstract method inside the parent class and implement in the child classes.
