问为什么我的代码总是打印数组中的第一个数据？

EN

i = 0
one_adult = [20.00,30.00]
one_child = [12.00,18.00]
one_senior = [16.00,24.00]
family_ticket = [60.00,90.00]
groups_of_six = [15.00,22.50]
lion_feeding = 2.50
penguin_feeding = 2.00
evening_barbecue = 5.00


Ticket_Type = ["one_adult",one_adult[i],"one_child",one_child[i],"one_senior",one_senior[i],"family_ticket",family_ticket[i],"groups_of_six",groups_of_six[i]]


Attractions_1day = ["lion_feeding",lion_feeding,"penguin_feeding",penguin_feeding]
Attractions_2day = ["lion_feeding",lion_feeding,"penguin_feeding",penguin_feeding,"evening_barbecue",evening_barbecue]


option = input("are you buying tickets for one day? (yes or no)")
if option == "yes" :
  print()
  print("These are ticket types available for one day tickets and their prices $")
  print()
  print(Ticket_Type)
  print()
  print("These are the attractions available for one day tickets and their prices $")
  print()
  print(Attractions_1day)
elif option == "no" :
  i = i + 1
  print()
  print("These are ticket types available for two day tickets and their prices $")
  print()
  print(Ticket_Type)
  print()
  print("These are the attractions available for two day tickets and their prices $")
  print()
  print(Attractions_2day)
