Question

The program needs to be in python :

First, create a BankAccount class. Your class should support the following methods: class BankAccount (object): """Bank Account protected by a pin number.""" def (self, pin) : init "n"Initial account balance is 0 and pin is 'pin'."" self.balance - 0 self.pin pin def deposit (self, pin, amount): """Increment account balance by amount and return new balance.""" def withdraw (self, pin, amount): """Decrement account balance by amount and return amount withdrawn.""" def get balance (self, pin): """Return account balance. def change_pin (self, oldpin, newpin) : ""Change pin from oldpin to newpin.""" As you implement your BankAccount class, you should think about the following: init What should happen if the wrong pin is provided for any of the methods (other than which is setting the initial pin)? What should happen if you try to withdraw more than is in the account? Does your bank account behave as you expect? Try depositing and/or withdrawing change, instead of whole dollar amounts. Do you want your real bank account to behave this way? Second create a SavingsAccount class that behaves just like a BankAccount, but also has an interest rate and a method that increases the balance by the appropriate amount of interest. Finally, write a main() to demo your savings account class (which automatically demos your bank account class). Create one instance of SavingsAccount, present a menu offering a few actions, and perform the action the user requests. 1. Deposit 2. Withdraw 3. Get balance 4. Change PIN 5. Add interest

thanks for the question, here is the complete program in python.
