In each of the two classes, the initializers have already been defined for you.

Methods in the Account class

In line 7, we have defined the withdrawal(amount) method. It takes a number, amount, as an input parameter and subtracts it from the balance.

In line 11, we have defined the deposit(amount) method. It takes a number, amount, as an input parameter and adds it to the balance.

In line 15, we have defined the getBalance() method that returns the value of balance.

Methods in the SavingsAccount class

We have defined the interestAmount() method that returns the amount of interest depending on the value of the interestRate defined at the time of the creation of the object.

class Account:  # parent class
    def __init__(self, title=None, balance=0):
        self.title = title
        self.balance = balance
    
    # withdrawal method subtracts the amount from the balance
    def withdrawal(self, amount):
        self.balance = self.balance - amount
    
    # deposit method adds the amount to the balance
    def deposit(self, amount):
        self.balance = self.balance + amount
    
    # this method just returns the value of balance
    def getBalance(self):
        return self.balance


class SavingsAccount(Account):
    def __init__(self, title=None, balance=0, interestRate=0):
        super().__init__(title, balance)
        self.interestRate = interestRate
    
    # computes interest amount using the interest rate
    def interestAmount(self):
        return (self.balance * self.interestRate / 100)


obj1 = SavingsAccount("Steve", 5000, 10)
print("Initial Balance:", obj1.getBalance())
obj1.withdrawal(1000)
print("Balance after withdrawal:", obj1.getBalance())
obj1.deposit(500)
print("Balance after deposit:", obj1.getBalance())
print("Interest on current balance:", obj1.interestAmount())
