Python实现简单的购物小程序
源代码:

product_list = [('Iphone',5800),('Mac Pro',9800),('Bike',800),
                ('Watch',10600),('Coffee',31),('Alex Python',120)]
shopping = []
salary = input('Inpit your salary:')
if salary.isdigit():
    salary = int(salary)
    while True:
        for index,item in enumerate(product_list):
            print(index,item)
        user_chioce = input("选择你要买啥?》》》:")
        if user_chioce.isdigit():#是不是数字
            user_chioce = int(user_chioce)
            if user_chioce < len(product_list) and user_chioce >=0:
                p_item = product_list[user_chioce]
                if p_item[1] <= salary: #买的起
                    shopping.append(p_item)
                    salary-=p_item[1]
                    print("Added %s into shopping cart,your current balance is \033[31;1m%s\033[0m" %(p_item,salary))
                else:
                    print('\033[41;1m你的余额只剩[%s],不足于购买该物品\033[0m'%(salary))
            else:
                print('商品不存在')


        elif user_chioce == 'q':

            print('\033[31;1m------你已购买的商品-------\033[0m')
            for p in shopping:
                print(p)
            print("你的余额还有:\033[32;1m%s\033[0m"%(salary))
            exit()
        else:
            print("输入有误,请重新输入")
