hi everyone,
please i need help with this assignment. I have written a code and i still
get an error. please help me debug my code.
instructions:
- Create a constructor that takes in an integer and assigns this to a
`balance` property.
- Create a method called `deposit` that takes in cash deposit amount and
updates the balance accordingly.
- Create a method called `withdraw` that takes in cash withdrawal amount
and updates the balance accordingly. if amount is greater than balance
return `"invalid transaction"`
- Create a subclass MinimumBalanceAccount of the BankAccount class
My code:
class BankAccount(object):
def __init__(self, balance):
self.balance = balance
def deposit(self, amount):
self.amount=amount
self.balance += amount
return self.balance
def withdraw(self, amount):
self.amount=amount
if(amount > self.balance):
return ("Amount greater than available balance.")
else:
self.balance -= amount
return self.balance
class MinimumBalanceAccount(BankAccount):
def __init__(self, minimum_balance):
BankAccount.__init__(self)
self.minimum_balance = minimum_balance
act = BankAccount(5)
act.deposit(400)
act.withdraw(200)
print act.balance
error message:

What do the instructions say that `withdraw` should return if the amount
is greater than the balance?
What would your code return in such a case?
