Question

TICKET_PRICE = 10
tickets_remaining = 100  
def calculateprice(numtickets):
    result = numtickets * TICKETPRICE
while ticketsremaining > 0:
  print("There are {} tickets remaining.".format(ticketsremaining))
  name = input("What is your name?
")
  numberoftickets = (input("How many tickets would you like {}?
".format(name)))
  try:
      numberoftickets = int(numberoftickets)
      if numberoftickets > ticketsremaining:
          raise ValueError(" There are only {} tickets remaining.".format(ticketsremaining))
      # Raise value error if request is for more tickets than are available
  except ValueError as err:
    #include error text in the output
      print("Make sure you enter a valid number and try again.{}".format(err))
  else:
      total = calculateprice(numberoftickets)
      print("{}, your total is {}.".format(name, total))
      proceed = input("Would you like to proceed {}? Y or N
".format(name))
      if proceed.capitalize() == "Y":
        # TODO: Gather CC info
        print("Sold!")
        ticketsremaining = ticketsremaining - numberoftickets
        print(ticketsremaining, "Ticket remaining.")
      elif tickets_remaining == 0:
        break
