Answer:
class Car:
def __init__(self):
self.model_year = 0
# TODO: Declare purchase_price attribute
self.purchase_price = 0
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
def print_info(self):
print("Model year: ",self.model_year)
print("Purchase year: ",self.purchase_price)
print("Current value: ",self.current_value)
def 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()
if __name__ == "__main__":
main()
Explanation:
The Car class in the python program is used to create a car object instance with class methods model_year, purchase_price, and calc_current_value, which accepts as arguments, year, price and current_year respectively. The main function runs if only the python module is run and interpreted to print out the year and current price of a car object instance defined.
