“我正在编写代码以提示用户用餐，并告知他们GCT之前和之后的费用”

上下文/背景： 曼彻斯特一家小型快餐店的老板米切尔（Mitchell）先生决定，他要一家商店使用计算机化系统。您需要编写一个程序来接受基于菜单的来自客户的订单和现金。然后，程序应计算并显示订单成本，包括GCT金额和客户变更。订单包括餐点，饮料和小菜。每个项目应有一个单独的菜单。选择每个项目时，应采用16.5％的GCT来产生总成本。然后，客户应该能够自己支付餐费，如果金额大于或小于总费用，则应采取适当的措施。打印出交易收据，包括购买的物品及其价格，GCT之前的总成本，GCT之后的总成本，客户支付的总金额以及客户收到的零钱。

gct= 0.165
order=0 
print("=============================Welcome to Mitchell's==========================")
print("====================================={MEALS}===================================")
print(" 1: Fried chicken and Rice: $400 " ," 2: Curred Chicken : $400 "," 3: Bbq Chicken : $450 "," 4: Fry Fish : $500 ")
print('\n')
print("===================================={DRINKS}===================================")
print("Water : $80 ","Soda : $100 ","Smoothie : $150")
print('\n')
print("===================================={SIDES}=====================================")
print("Fries : $200 ","Pasta : $100 ","Coleslaw : $100 ")
print('\n')
meal=[" 1: Fried chicken and Rice" ," 2: Curred Chicken"," 3: Bbq Chicken"," 4: Fry Fish"]
drink=["Water","Soda","Smoothie"]
sides=["Fries","Pasta","Coleslaw"]
print('\n')
choice=(input("Type of order: 1: Meals  2:Drinks  3:Sides: "))
if choice == 1:
     x= meal.copy()
def MEAL(gct,order):
    select=(int(input("Select Meal Choice: ")))
    amount=(int(input(" Quantity: ")))
    if select==1:
        food = 400
        total = (food*gct)+food
        final = total*amount
        print(final)
    elif select==2:
        food = 400
        total =(food*gct)+food
        final = total*amount
        print(final)
    elif select==3:
        food = 450
        total =(food*gct)+food
        final = total*amount
        print(final)
    elif select==4:
        food = 500
        total =(food*gct)+food
        final = total*amount
        print(final)

    num=(int(input("Do you want to add another meal 1 for yes 2 for No")))
    if num == 1:
        order=final
        final = final*amount
        print(order)
        MEAL(gct,order)
    elif num == 2:
        final =order+final
        order=final+order
        print(final)
        print(order)
        exit
MEAL(gct,order)

问题：

问题结束时，每当我按num=(int(input("Do you want to add another meal 1 for yes 2 for No")))时我就有1没问题，但是如果我按2，我的计算就不正确，例如，如果上面的食物价格为$ 400在GCT之前，GCT之后应该给$ 466，但不是给我那么多的钱，而是给与更多或相同的$ 400

我的计算有问题，到目前为止，我已经编写了代码，下面是问题
