Question

In python:

Make a BankAccount class.
The class should have the initial balance be set
to a parameter passed into the constructor, but should be 0 if no such parameter is passed in.
It should have a method called "withdraw" that withdraws an amount that's supplied
as a parameter and returns the new balance. It should also have a method called "deposit"
that deposits an amount that's supplied as a parameter and returns the new balance.
Both "withdraw" and "deposit" should alter the account's balance.
Have a method that return a current balance.

Your function should construct a "banking", make some withdraw and deposits and print out
your current balance. It should return a current balance

Answer 1

class BankAccount:
    def __init__(self, initialBalance=0):
        self.balance = initialBalance

    def deposit(self, amount):
        self.balance += amount
        return self.balance

    def withdraw(self, amount):
        self.balance -= amount
        return self.balance

    def getBalance(self):
        return self.balance


def main():
    account = BankAccount(1000)
    print("Balance is " + str(account.getBalance()))
    print("Withdrawing 500")
    print("Balance is " + str(account.withdraw(500)))
    print("Depositing 700")
    print("Balance is " + str(account.deposit(700)))


main()
