深夜十点半（二）——我的第二个Python程序“购物车”

这个程序的关键点为：

1、列表类型的数据结构设计

2、列表类型的数据结构查找方法

#购物车程序

#1. 启动后，输入用户工资

#2. 产品列表

product_list = [
    ('Iphone',5800),
    ('Iwatch',5800),
    ('Icar',15800),
    ('Coffee',20),
]
#1. 启动后，输入用户工资
salary = input("Input your salary:")
shopping_list = []
if salary.isdigit():
    salary = int(salary)
while True:
    for index,item in enumerate(product_list):
        print(index,item)
    choice = input("Input your choice:")
    if choice.isdigit():
        choice = int(choice)
        if choice < len(product_list) and choice >= 0:
            p_item = product_list[choice]
            if p_item[1] <= salary: #买得起
                shopping_list.append(p_item)
                salary -= p_item[1]
                print("Added %s into shoppint cart, your current balance is %s" %(p_item,salary))
        else:
            print("Product is not exist")
    elif choice == 'q':
        print("Your current balance is ", salary)
        break
