Question

I'm having trouble with- Write a simple ATM program. Ask the user to enter their account number, and then print their beginning balance. (Just make one up). Then ask them if they want to make a deposit or a withdrawal. Depending on their selection, call a function to perform the action that they wish. Then print the new balance. They should be able to do as many transactions as they wish, so use iteration here. /// I'm using python 3.4.1 Where exactly do I put the made up balance? I have been able to make it appear by adding a number into the print ('Balance: '),balance line but then if I make a deposit or withdrawl it does nothing to the displayed balance.. I have been running the following code:

def getBalance(choice, balance):
if(choice== 1 or choice==2):
amount=float(input("Enter amount: "))
if(choice== 1):
balance = balance + amount
if(choice== 2):
balance = balance - amount
return balance

def bank():

balance = 650
accountNum = input("Enter account number: ")
choice= 1
print ('Balance: '),balance
while (choice== 1 or choice==2):
#ask for deposit or a withdrawal or exit
choice =float(input("Enter 1 for Deposit, 2 for Withdrawl, 3 to Exit: "))
balance = getBalance(choice, balance)
#print total amount
print ('Balance: '),balance


def main():
bank()

main()
