What is wrong with this code and why it isn't working. 

class BankAccount: def init (self) : self.balance = 0.00 def deposit (self, amount) : self.balance += amount def withdraw (self, amount) : if self.balance >= amount: self.balance -= amount else: print ("Not enough money in the account. Withdrawal failed. ") def getBalance (self) : return self.balance a = BankAccount () print (a.getBalance ()) a.deposit (100.00) print (a.getBalance ()) a.withdraw (200.00) print (a.getBalance ()) a.withdraw (20.00) print (a.getBalance ())
