Question

How would I modify this Python Program to include two different if statement structures? "For this program, decisions may include adding different charges to a tables' check based on what the diner orders, and/or deciding when to quit the program, among other possibilities. "

def display_menu_items():
   print("item cost")
   print("1.item-1 5")
   print("2.item-2 10")
   print("3.item-3 15")
   print("4.item-4 50")
   print("5.item-5 25")
   print("6.item-6 2")
   print("7.item-7 26")

def main():
   print("Enter -1 to quit manager or any other number to continue")
   enter_to_quit=int(input())
   if (enter_to_quit==-1):
       quit()
   print("enter table number")
   table_number=int(input())
  
   print("enter no.of diners (maximum limit 4)")
   number_of_diners=int(input())
  
   print("select an item and enter -1 to exit")
   items=[]
   item_number=[]
   select=0
   ch=[0,5,10,15,50,25,2,26]
   display_menu_items()
  
   while ( select is not -1):
       items.append(ch[select])
       item_number.append(select)
       select=int(input())
  
   total_items_cost=0
  
   for i in items:
       total_items_cost=total_items_cost+i
  
   print("Total cost without tax =",total_items_cost)
   total_cost=total_items_cost+(total_items_cost/100)*8
  
   print("cost for individual diner =",total_cost/number_of_diners)
   print("total cost with tax = ",total_cost)
   print("suggestions for tip 1.10% 2.15% 3.20% 4.25% ")
  
   tip=int(input())
   tip_list=[10,15,20,25]
   total_tip=tip_list[tip]
   total_tip=(total_cost/100)*total_tip
  
   print("table information")
   print("table no:- ",table_number)
   print("selected items:-")
  
   item_list=["item-1","item-2","item-3","item-4","item-5","item-6","item-7"]
  
   for i in range(1,len(items)):
       print(item_list[item_number[i]-1])
   print("total cost= ",total_cost)
   print("tip= ",total_tip)
   print("total cost with tip= ",total_cost+total_tip)
   main()
