Please, what is the solution to this python code:
OOP LAB Create a class called BankAccount
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
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')
Thank you…
