# property decorator, getters and setters methods.

    print(acc.fullName)              # Notice that we can access the method for our class BankAccount without
                                     # parenthesis! This is beacuse of property decorator

    # acc.fullName = 'Omkar Pathak'    #This throws an error! Hence setter decorator should be used.
    acc.fullName = 'Jagdish Pathak'
    print(acc.fullName)
