Complete the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information. Ex: If the input is: 2011 18000 2018 where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs: Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770 Note: print_info() should use three spaces for indentation. class Car: def __init__(self): self.model_year = 0 # TODO: Declare purchase_price attribute self.current_value = 0 def calc_current_value(self, current_year): depreciation_rate = 0.15 # Car depreciation formula car_age = current_year - self.model_year self.current_value = round(self.purchase_price * (1 - depreciation_rate) ** car_age) # TODO: Define print_info() method to output model_year, purchase_price, and current_value if __name__ == "__main__": year = int(input()) price = int(input()) current_year = int(input()) my_car = Car() my_car.model_year = year my_car.purchase_price = price my_car.calc_current_value(current_year) my_car.print_info()
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Complete the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information.
Ex: If the input is:
2011
18000
2018
where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs:
Car's information:
Model year: 2011
Purchase price: 18000
Current value: 5770
Note: print_info() should use three spaces for indentation.
class Car:
def __init__(self):
self.model_year = 0
# TODO: Declare purchase_price attribute
self.current_value = 0
def calc_current_value(self, current_year):
depreciation_rate = 0.15
# Car depreciation formula
car_age = current_year - self.model_year
self.current_value = round(self.purchase_price * (1 - depreciation_rate) ** car_age)
# TODO: Define print_info() method to output model_year, purchase_price, and current_value
if __name__ == "__main__":
year = int(input())
price = int(input())
current_year = int(input())
my_car = Car()
my_car.model_year = year
my_car.purchase_price = price
my_car.calc_current_value(current_year)
my_car.print_info()
