py脚本汇集

　　1.商场购物

　　脚本运行时，打印商品列表，根据用户的交互式信息实现大体的购物流程；

# Author: kazihuo
salary = input("Please input your salary:")
product_list = [
    ('iphone',5800),
    ('laptop',7700),
    ('bike',500),
    ('book',53),
    ('watch',15)
]
shopping_list = []
if salary.isdigit():
    salary = int(salary)
    while True:
        for item in product_list:
            print(product_list.index(item),item)
        user_choice = input("Please choice:")
        if user_choice.isdigit():
            user_choice = int(user_choice)
            if user_choice > -1 and user_choice < len(product_list):
                p_item = product_list[user_choice]
                if p_item[1] <= salary:
                    shopping_list.append(p_item)
                    salary -= p_item[1]
                    #print("Added %s into cart,current balance is "%p_item,salary )
                    print("Added %s into shopping cart,your current balance is \033[31m%s\033[0m" %(p_item,salary))
                else:
                    print("your balance is \033[41;37m%s\033[0m,not enough!" %salary)
            else:
                print("product code %s is not exist!"%user_choice)
        elif user_choice == 'q':
            print("---------shopping list---------")
            for p in shopping_list:
                print(p)
            print("your current balance:",salary)
            exit()
        else:
            print("Invalid option!")

　　 2.三级菜单

　　利用字典特性实现三级菜单的功能，用户根据选择一级一级的进入；
