Create a class called BankAccount

and updates the balance accordingly. if amount is greater than balance
return `"invalid transaction"`
.Create a subclass MinimumBalanceAccount of the BankAccount class
Please i need help on this i am a beginer into python programming.
Also below is a test case given for this project
import unittest
class AccountBalanceTestCases(unittest.TestCase):
def setUp(self):
self.my_account = BankAccount(90)
def test_balance(self):
self.assertEqual(self.my_account.balance, 90, msg='Account Balance
Invalid')
def test_deposit(self):
self.my_account.deposit(90)
self.assertEqual(self.my_account.balance, 180, msg='Deposit method
inaccurate')
def test_withdraw(self):
self.my_account.withdraw(40)
self.assertEqual(self.my_account.balance, 50, msg='Withdraw method
inaccurate')
def test_invalid_operation(self):
self.assertEqual(self.my_account.withdraw(1000), "invalid
transaction", msg='Invalid transaction')
def test_sub_class(self):
self.assertTrue(issubclass(MinimumBalanceAccount, BankAccount),
msg='No true subclass of BankAccount')
my solution is:
class BankAccount(object):
def __init__(self, initial_balance):
self.balance = initial_balance
def deposit(self, amount):
self.balance +=amount
def withdraw(self, amount):
if self.balance>= amount:
self.balance -= amount
else:
return invalid transaction
a1 = BankAccount (90)
a1.deposit(90)
a1.withdraw(40)
a1.withdraw(1000)
class MinimumBalanceAccount(BankAccount):
def __init__(self):
BankAccount.__init__(self,minimum_balance)
self.minimum_balance = minimum_balance
my_account = BankAccount(90)
my_account.withdraw(40)
print my_account.balance
It keeps alerting me that,"Error running your script".Where might I have
gone wrong?Please help..
Most probably there's extra information available on the "Error running
your script" message. You should examine that.
Meanwhile, I think the line "return invalid transaction" provides a clue.
