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.

how do you call the squares method to compute the first five squares and store the result in an array numbers

IRINA_888 [86]

Answer:

The method can be called using:

int[] returnarray = Squares();

Where returnarray represents the name of the array

Explanation:

To answer this, I will make an assumption that the Square method is an int array method (i.e. it returns array).

So, to call the method from main, an array has to be declared to get the values:

int[] returnarray = Squares();

Then an iteration is created to iterate through the array in order to print the array elements.

for (int i = 0; i < returnarray.length; i++)

System.out.print(returnarray[i]+ " ");

-------------------------------------------------------------------------------------------

The answer ends here

-------------------------------------------------------------------------------------------

As an addition, the complete program that includes the method and the main is:

public class Main{

public static int [] Squares(){

int [] arr = new int[5];

for(int i = 1;i<6;i++){

arr[i-1] = i*i;

}

return arr;

}

public static void main(String[] args) {

int[] returnarray = Squares();

for (int i = 0; i < returnarray.length; i++)

System.out.print(returnarray[i]+ " ");

}

}
