Question

我的任务如下

为在线食品服务编写菜单，可选择4种不同的菜肴，即：墨西哥

每种菜肴应至少有5种不同的选择，如咖喱，咖喱酱，热咖喱等。它应该用订单号打印出用户的最终订单。

我的问题是如何将订单放在一起，然后加入列表中的一些字符串，例如：添加热到蔬菜咖喱，但目前它按不同的顺序排列

最后，为了使代码高效，我应该使用def函数吗？这是当前的代码。随机导入

Answer 1

要将项目添加到列表末尾，您需要使用

foodList.append(choice);

这样您就不必担心.insert()所涉及的索引编制。

这意味着您必须重新排列if语句或更好地了解insert()：https://docs.python.org/2/tutorial/datastructures.html

如何在列表中将字符串连接在一起？
