Python作业之购物商城

作业：购物商场

1、商品展示，价格

2、银行卡余额

3、付账

程序流程图如下：

代码如下：

 ShopDisplay = {'clothes1':'','jeans':'','shoes':'','hat':'','clothes2':''}
 print(ShopDisplay)
 ShoppingCartPrice = []
 ShoppingCart = {}
 while True:
     thing = input("You want to buy :")

     price = ShopDisplay['%s' %thing]
     ShoppingCart.update({ '%s' %thing:'%s' %price })

     ShoppingCartPrice.append('%s' % price)

     answer = input("Do you want to continue buy something else?Please say yes or no:")
     if answer == 'yes':
         continue
     else:
         break

 def shit():
     sum = 0
     TotalMoney = 1000
     for i in ShoppingCartPrice:
         sum = sum + int(i)
         TotalMoney = TotalMoney - sum
         if TotalMoney > 0:
             a = input("Do you really want to buy tins ?Please enter yes or no !\n")
             if a == 'yes':
                 print("Successful,wish you a happy shopping!\n")
                 exit()
             else:
                 print("Thanks you for come to my shop!")
                 exit()
         else:
             print("Sorry,you have not enough money!Please remove somethings!\n")

 sum = 0
 TotalMoney = 1000
 for i in ShoppingCartPrice:
     sum = sum + int(i)
     TotalMoney = TotalMoney - sum
 if TotalMoney > 0 :
     a = input("Do you really want to buy tins ?Please enter yes or no !\n")
     if a == 'yes':
         print("Successful,wish you a happy shopping!\n")
         exit()
     else :
         exit()
 else :
     print("Sorry,you have not enough money!Please remove somethings!\n")

     while True:
         print("Your shopping cart have this thing:\n")
         print(ShoppingCart)

         print("If you don't want to del,please enter '.'\n")
         del_thing = input("Please input the goods that you don't want to buy:\n")
         if del_thing == '.':
             break

         s = ShoppingCart['%s' % del_thing]
         ShoppingCart.pop('%s' % del_thing)

         ShoppingCartPrice.remove(s)

 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
