Question

1) Using the Object-Oriented Programming Paradigm,implement the necessary code in Python creating a ‘Car’ class with a constructor that stores all the Car information (ID, MAKE, MODEL, YEAR , COLOR, MILEAGE, PRICE_TO_DEALER, SALE_PRICE, PROFIT) as attributes.

2) Implement and add the following methods to the ‘Car' class in Question 1.

a) necessary getter methods

b) necessary setter methods

c) method to display all the information to the screen

d) a method to calculate the profit

Answer 1

The python code to implement car class is below

# creating class named car
class car:
  
PROFIT=0 # initilizing the profit
  
# using constructure to initilize the car object   
def __init__(self,ID, MAKE, MODEL, YEAR , COLOR, MILEAGE, PRICE_TO_DEALER, SALE_PRICE):
self.ID=ID
self.MAKE=MAKE
self.MODEL=MODEL
self.YEAR=YEAR
self.COLOR=COLOR
self.MILEAGE=MILEAGE
self.PRICE_TO_DEALER=PRICE_TO_DEALER
self.SALE_PRICE=SALE_PRICE
  
# declaring the necessary getters and setters method
  
# getter and setter of make
def set_make(self, MAKE):
self.MAKE = MAKE
  
def get_make(self):   
return self.Make
  
# getter and setter of model
def set_model(self, MODEL):
self.MODEL = MODEL
  
def get_model(self):   
return self.MODEL
  
# getter and setter of MILEAGE
def set_mileage(self, MILEAGE):
self.MILEAGE = MILEAGE
  
def get_mileage(self):   
return self.MILEAGE
  
# getter and setter of PRICE_TO_DEALER   
def set_pricetodealer(self, PRICE_TO_DEALER):
self.PRICE_TO_DEALER = PRICE_TO_DEALER
  
def get_pricetodealer(self):   
return self.PRICE_TO_DEALER
  
# getter and setter of SALE_PRICE
def set_saleprice(self,SALE_PRICE):
self.SALE_PRICE=SALE_PRICE
  
def get_saleprice(self):
return self.SALE_PRICE
  
# function to calculate the PROFIT
def calculate_profit(self,SALE_PRICE,PRICE_TO_DEALER):
self.PROFIT=(SALE_PRICE-PRICE_TO_DEALER)
  
# function to return the calculate_profit   
def get_profit(self):
self.calculate_profit(self.SALE_PRICE,self.PRICE_TO_DEALER)
return self.PROFIT
  
# function to display the car information
def display_car_info(self):
print('The ID of the car is: ',self.ID)
print('The Make of the car is: ',self.MAKE)
print('The MODEL of the car is: ',self.MODEL)
print('The YEAR of the car is: ',self.YEAR)
print('The COLOR of the car is: ',self.COLOR)
print('The MILEAGE of the car is: ',self.MILEAGE)
print('The PRICE_TO_DEALER of the car is: ',self.PRICE_TO_DEALER)
print('The SALE_PRICE of the car is: ',self.SALE_PRICE)
self.calculate_profit(self.SALE_PRICE,self.PRICE_TO_DEALER)
print('The PROFIT of the car is: ',self.PROFIT)
  
  
new_car=car(12,'skoda','superb',2005,'white',15,3000,3500)
print("Displaying CAR information after object initilization:\n ")
new_car.display_car_info()

print("\nChanging the MAKE to AUDI, SALE_PRICE to 10000 and PRICE_TO_DEALER to to 8000 :\n")

new_car.set_saleprice(10000)
new_car.set_pricetodealer(8000)
new_car.set_make('Audi')
new_car.display_car_info()
