for tries in range(0, 4): 
    deposit = input("Enter amount to deposit: ") 
     try: 
      deposit = int(deposit) 
      if deposit < 0: 
       raise "invalid output" 
     except: 
      print("This transaction cannot proceed. You entered amount in negative") 
      tries += 1 
     else: 
      print("Deposited: \tPKR ", deposit) 
      print("Current Balance: \tPKR %d"%(currentBalance + deposit)) 
      currentBalance += deposit 
      print("Would you like to do any more Transaction?")
