I've never used classes and stuff much so I gave it a go. (But I 
wouldn't submit this if it's an assignment).
class ac:
 balance=0
 def __init__(self,openbal):
 if openbal>0:
 self.balance=openbal
 print ("Opened account; opening balance",self.balance)
 else:
 print ("Invalid opening balance:",openbal)
 def payin(self,amount):
 if amount>0:
 self.balance+=amount
 print ("Paid in:",amount," New balance:",self.balance)
 return 1
 else:
 print ("Paying in invalid sum",amount)
 return 0
 def takeout(self,amount):
 if amount<=0:
 print ("Invalid withdrawal amount",amount)
 return 0
 elif amount>self.balance:
 print ("Not enough funds")
 return 0
 else:
 self.balance-=amount
 print ("Paid out:",amount," New balance:",self.balance)
 return 1
x=ac(100)
x.payin(34)
x.takeout(70)
x.takeout(1000000)
