 3 ShoppingCartPrice = []
 4 ShoppingCart = {}
 5 while True:
 6     thing = input("You want to buy :")
 7 
 8     price = ShopDisplay['%s' %thing]
 9     ShoppingCart.update({ '%s' %thing:'%s' %price })
10 
11     ShoppingCartPrice.append('%s' % price)
12 
13     answer = input("Do you want to continue buy something else?Please say yes or no:")
14     if answer == 'yes':
15         continue
16     else:
17         break
18 
19 
20 def shit():
21     sum = 0
22     TotalMoney = 1000
23     for i in ShoppingCartPrice:
24         sum = sum + int(i)
25         TotalMoney = TotalMoney - sum
26         if TotalMoney > 0:
27             a = input("Do you really want to buy tins ?Please enter yes or no !\n")
28             if a == 'yes':
29                 print("Successful,wish you a happy shopping!\n")
30                 exit()
31             else:
32                 print("Thanks you for come to my shop!")
33                 exit()
34         else:
35             print("Sorry,you have not enough money!Please remove somethings!\n")
36 
37 
38 
39 sum = 0
40 TotalMoney = 1000
41 for i in ShoppingCartPrice:
42     sum = sum + int(i)
43     TotalMoney = TotalMoney - sum
44 if TotalMoney > 0 :
45     a = input("Do you really want to buy tins ?Please enter yes or no !\n")
46     if a == 'yes':
47         print("Successful,wish you a happy shopping!\n")
48         exit()
49     else :
50         exit()
51 else :
52     print("Sorry,you have not enough money!Please remove somethings!\n")
53 
54     while True:
55         print("Your shopping cart have this thing:\n")
56         print(ShoppingCart)
57 
58         print("If you don't want to del,please enter '.'\n")
59         del_thing = input("Please input the goods that you don't want to buy:\n")
60         if del_thing == '.':
61             break
62 
63         s = ShoppingCart['%s' % del_thing]
64         ShoppingCart.pop('%s' % del_thing)
65 
66         ShoppingCartPrice.remove(s)
67 
68 shit()

 

　　

代码很简陋，作业功能基本都实现了，将就着看吧。。。。日后再来优化
