Question

New to python if you can add screenshort also, i am using python 3

7.3 (The Account class) Design a class named Account that contains A private int data field named id for the account. A private float data field named annualInterestRate that stores the current A constructor that creates an account with the specified id (default 0), initial The accessor and mutator methods for id, balance, and annualInterestRate A private float data field named balance for the account. interest rate. balance (default 100), and annual interest rate (default 0) A method named getMonthlyInterestRateO that returns the monthly interest rate. A method named getMonthlyInterestO that returns the monthly interest. A method named withdraw that withdraws a specified amount from the account. ·A rnethod named deposit that deposits a specified annount to the account. Draw the UML diagram for the class, and then implement the class. (Hint: The method getMonthlyInterest is to return the monthly interest amount, not the interest rate. Use this formula to calculate the monthly interest: balance* monthlyInterestRate. monthlyInterestRate is annualInterestRate 12. Note that annual InterestRate is a percent (like 4.5%). You need to divide it by 100.) Write a test program that creates an Account object with an account id of 1122, a balance of $20,000, and an annual interest rate of 4.5%. Use the withdraw method to withdraw $2,500, use the deposit method to deposit $3,000, and print the id, balance, monthly interest rate, and monthly interest.
