Unfortunately this is still far from what is - presumably - desired:

class account:  # (doesn't inherit from blah blah)
    def __init__(self, initial):
        self.balance = initial  # you have to create an instance-Variable
                   # so the account will remember its balance
    def deposit(self, amount):
        self.balance += amount

    ....
etc.
To work successfully with classes needs certainly reading some
introductory material - I think Alan's tutor wouold be a fine starting 
point:
