romanna [79]

<h2>Hello!</h2>

The answer is:

Optical disks are circular disks used as storage for binary data usually made of polycarbonate. The data is stored in the disc using a laser machine and accessed using a laser diode illuminating the data path in an optical disc drive.

CD: Compact Discs are the most basic optical disk used today, with only a capacity that goes from 0.7 GB (700 MB) to 0.84 GB (840 MB).

DVD: Digital Versatile Discs increase the storage up to 6 times compared with a CD, the capacity of DVDs optical disks goes from 4.7 GB (4700 MB) to about 17 GB(17000 MB).

UDO: Ultra Density Optical have high capacity storage that goes from 30 GB (30000 MB) to about 60 GB (6000 MB).

I need help with completing this python code.Complete the Car class by creating an attribute purchase_price (type int) and the m

netineya [11]

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.
