我已经上传了我的全部代码,因为我猜我遗漏了一些你需要知道的地方。你知道吗
我本来想把我有问题的部分用粗体写出来,但没用。所以
Hydration = ("Cola","Fanta","Coffee")
Nutrition = ("Bacon", "Steak","Beans")
print ("Hydration Menu:")
print (Hydration)
print ("Nutrition Menu:")
print (Nutrition)
cost =[]
cost[Hydration] = 100
cost[Nutrition] = 60
我试着将变量营养和水合作用赋值为60和100,这样程序就会知道从你的信用中扣除多少,但它不断返回变量“成本”没有定义。此外,代码似乎没有认识到产品(如上所示)是有效的条款,尽管事实上,他们应该连接到变量水合和营养。你知道吗
如你所见,我对代码的艺术不是很了解。所以我才需要帮助。先谢谢你。你知道吗
你需要一本字典而不是一张单子
或者你想把一个成本和列表中的每个成员联系起来
