如何在列表中连接字符串？

Question

我的任务如下

写一个菜单，为一个在线食品服务与选项4种不同的菜肴，即：墨西哥菜

每道菜至少要有5种不同的选择，比如咖喱、咖喱酱、热咖喱等等。它应该打印出带有订单号的用户最终订单。你知道吗

我的问题是，如何将顺序组合在一起，然后将列表中的一些字符串连接起来，例如：add hot to veg curry，但目前它的顺序不同

最后，为了提高代码的效率，我应该使用def函数吗？ 这是当前代码。 随机导入

            print("Welcome to Hungry Horse...")
            print("We have wide range of food choice from all around the world")
            print("We have food choices from: Indian / Italian / Chinese / Mexican")
            foodList = ([])

            drinkCho = input("Lets start with drinks. State if you would like drinks yes or no").lower()
            if drinkCho == "yes":
                drinkCho2 = input("Which drink do you want? We have option of:Coke / Fanta / Cobra / Water / FruitShoot").lower()
                if drinkCho2 == "coke":
                            foodList.insert(1,drinkCho2)
                            print("You have chosen coke.A great choice")
                if drinkCho2 == "fanta":
                            foodList.insert(2,drinkCho2)

            print ("Your final order", foodList ," Your order number is", rnd, "Please wait until we process your order")

要将项目添加到列表的末尾，您需要使用

foodList.append(choice);

这样您就不必担心.insert()所涉及的索引。你知道吗

这意味着您要么重新排列if语句，要么更好地熟悉insert()：https://docs.python.org/2/tutorial/datastructures.html
