Python 如何编辑列表并显示其编辑内容？

我必须建立一个允许查看和编辑预订的航班预订系统，但我不知道如何使用我的代码来实现这一点。这是我到目前为止的代码，但我不知道如何编辑列表，然后在“预订”视图中打印名称。任何帮助都将不胜感激

def mainMenu():
  print("="*69)
  cstr = "Welcome to Airlines"
  print (cstr.center(69,'='))
  print("="*69)
  cstr = "CA Travel System 1.0 by "
  print (cstr.center(69, '#'))  
  print("="*69)
  print("option: Reserve First Class seat(rf), Reserve Coach seat(rc),Print(P),Change Reserve(C), Quit(q)")
  print("="*69)
  print("Enter 1 to buy a seat or Enter 2 to quit")
  mainAction= input("What would you like to do? ")
  clientNam = input("What name will be used for the reservation? ")
  seatLet = input("What seat letter would you perfer? Seats A and D are window and B and C are aisle(A-D) ")
  seatNum = input("What row number will you prefer? Rows 1-4 are first class. Row 5-15 are coach (1-15) ")

最好使用一个列表，而不是变量

l1

，

l2

等。您可以访问

seats[0][0]

或将其保存在字典中，这样您就可以使用字母

seats[“A”][0]

，然后您可以使用

seatLet[seatNum]
