Question

这是用户的购物车，计算其总数并列出产品。我很难在底部定义税收＆＃34; wdeposit＆＃34;我还有一些事要做。然后如何显示两个单独的总计。然后我打算用

while 1:
    action=input("press any key if you like to purchase otherwise type end to finish")
    if action=="end"
        break

我希望这将是一个很好的结局。希望有人可以帮我完成我的作业。提示会更有帮助，所以我可以学习，而不是实际上有人为我做。感谢。

#Welcome user to user display product and prices
print("Hello, welcome to the store")

if choice==4:
            wdeposit=wdeposit*.05
            print("$.05 deposit", wdeposit)

Answer 1

行wdeposit=wdeposit*.05应该基于瓶装水的数量（qofwater * 0.05）。您有if choice==4:两次，但您只需要一次。您可以将wdeposit计算放在同一个区块中，向用户询问他们想要购买多少瓶水。
