作业：购物商场

3、付账

程序流程图如下：

代码如下：

ShopDisplay = {'clothes1':'498','jeans':'128','shoes':'289','hat':'99','clothes2':'599'}
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 !
")
            if a == 'yes':
                print("Successful,wish you a happy shopping!
")
                exit()
            else:
                print("Thanks you for come to my shop!")
                exit()
        else:
            print("Sorry,you have not enough money!Please remove somethings!
")



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 !
")
    if a == 'yes':
        print("Successful,wish you a happy shopping!
")
        exit()
    else :
        exit()
else :
    print("Sorry,you have not enough money!Please remove somethings!
")

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

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