You did it inside the class definition, but you are trying to
use them outside the class - check the indentation...
> class AccountTransaction(object):
> def __init__(self, amount, time):
> self.amount = amount
> self.time = time
> def __repr__(self):
> def __self__(self, initial):
End of class definition because while is not indented to right level
incidentally what does __self__ do, thats a new one on me...
> while 1:
> print '''
Welcome to the Bank
Triple quoted strings save a lot of typing of print statements...
choice = int(raw_input('Enter your choice: '))
> if choice == 1:
> amount = raw_input ('Amount: ')
> elif amount < 0:
> raise ValueError, 'Deposites must be positive'
> elif self.balance - amount < 0:
This is not part of the class so self doesn't exist...
