writing a class

[Crypt Keeper]

It's a simple bank-type transaction program. User needs to input
initial starting balance, amount of deposits, amount of withdrawals.
Program needs to do the appropriate math and return status update
showing new balance, total deposits and total withdrawals.

I keep coming up with 2 different results...1 returns an error message
and the other finishes the program but the mathmematics is wrong (it
does not compute deposits and withdrawlas. It only returns intial
balance as new balance.)

Code for error message return is:

(formal code)
from Account import Account
from datetime import date

a = Account()
now = date.today()

print "As of",now,"balance is $",a.getbalance()

(class code)
class Account:
      
     def __init__(self, initial):
         self.balance = initial
     def deposit(self, amt):
         self.balance = balance + amt
     def withdraw(new, amt):
         self.balance = balance - amt
     def getbalance(self):
         return self.balance

Error message that gets returned is:

Traceback (most recent call last):
  File "C:\Python23\Module1a.py", line 4, in -toplevel-
    a = Account()
TypeError: __init__() takes exactly 2 arguments (1 given)



The code that returns new balance only is:

(class code)
class Account:

     def __init__(self, balance):
         self.balance = balance         
     def deposit(self, deposit):
         self.balance = self.balance + deposit
     def withdraw(self, withdraw):
         self.balance = self.balance - withdraw
     def getbalance(self, balance):
         self.balance = bal + deposit - withdraw
         return self.balance

(formal code)
from account1a import Account
from datetime import date

now = date.today()

a = Account()

bal = input("Enter amount of starting balance: $")
dpst = input("Enter amount of deposit: $")
wdrw = input("Enter amount of withdrawal: $")

print "As of",now,"balance is $",a.getbalance()


Appreciate all the assistance I might get.
