python购物车程序

 

 很基础的一个例子，主要是为了练习python的基础语法，要求如上，实现代码如下：

# coding=gbk
# _author:Administrator
# date: 2021/03/31

GoodsDic = {"iphone6s": 5800, "bicycle": 1500, "python book": 80, "coffee": 30, "mac book": 10000}
GoodsDic1 = {'1': "iphone6s", '2': "bicycle", '3': "python book", '4': "coffee", '5': "mac book"}
# print(GoodsDic1['1'])
salary = input("您的工资为？\n")
goodList = []
isExit = 1
while isExit:
    goodNum = input("请输入你要购买的商品序号：\n1.iphone6s,2.bicycle,3.python book,4.coffee,5.mc book,6.exit\n")
    for good in GoodsDic:
        if goodNum == '6':
            isExit = 0
            break
        if good == GoodsDic1[goodNum]:
            if int(salary) >= GoodsDic[good]:
                goodList.append(good)
                salary = int(salary) - GoodsDic[good]
                msg = "已购买%s，余额为：%s\n" % (good, salary)
                print(msg)
                break
            else:
                print("您的资金不足，请选择别的商品！")
                break

print("您购买了以下商品：\n")
for g in goodList:
    print(g+"\t")
msg = "余额为：%s,欢迎光临\n" % salary
print(msg)

输出结果：
