Some loans carry discount points. Each discount point requires the borrower to pay up-front an additional amount of money equal to 1% of the stated loan amount. For instance, for a $200,000 mortgage with 3 discount points, the purchaser must pay $6,000 immediately. Even though this payment has the effect of reducing the loan to $194,000, the monthly payment is calculated using a principal of $200,000. The up-front interest payment is tax deductible and the interest rate on a mortgage with points is slightly lower than the interest rate on a standard mortgage without points. Mortgages with discount points usually are advantageous to people who intend to keep their house for more than seven years. Create a class named MortgageWithPoints that is a subclass of the class Mortgage from Q1. The class should inherit the instance variables from its parent class, have an additional instance variable named numberOfPoints. The class should also have an additional method calculateCostOfPoints to calculate the cost of the points. Name this file (module) as mortgage_with_points. py. Note, the cost of the points is calculated as p × A⁄100, where p is the number of points and A is the principal. Then write another program that uses the class MortgageWithPoints to calculate the monthly payment where the (a) principal, (b) interest rate, (c) term, and (d) number of discount points are input by the user
