字典实现简单购物车程序

正在学习老男孩教育Alex老师的python视频课程，感谢。

 

版本1：自己瞎弄版
购物车：

#__author__ = 'Alex Wen'
# coding=gbk
Shopping={
    "1101":{"Mac pro":int("8880")},
    "1102":{"IPhone":int("5800")},
    "1103":{"Watch":int("500")},
    "1104":{"HuaWei P20":int("3780")},
    "1105":{"Pad":int("1200")}
}
Bought_List=[]#设置一个空列表用于存放已经购买的商品数据
print("商品列表-->",Shopping)
Blance=input("你的余额为>>>:")
if Blance.isdigit():
    Blance=int(Blance)
    while True:
        Buy_1=input("请输入要购买的商品编号>>>:")
        if Buy_1 in Shopping.keys():#输入商品编号
            Price_All=Shopping[Buy_1].values()#每一件商品的价格
            for Name_Goods in Shopping[Buy_1].keys():#把编号对应的商品名取出
                pass
            for Price in Price_All:#把输入编号对应的商品价格取出
                    if Price<=Blance:#买得起
                        Bought_List.append(Name_Goods)
                        Blance-=Price
                        print("把%s添加到购物车，你的余额为%s"%(Name_Goods,Blance))
                    else:
                        print("支付失败！你的余额为%s"%(Blance))
        elif Buy_1 == "q":
            print("----------商品清单-----------")
            for Totall_Goods in Bought_List:
                print(Totall_Goods)
            print("您目前的余额为%s"%(Blance))
        else:
            print("请输入正确的商品编号！谢谢！")

老男孩教育Alex老师版（基于列表）：

#__author__ = "Alex Li"


product_list = [
    ('Iphone',5800),
    ('Mac Pro',9800),
    ('Bike',800),
    ('Watch',10600),
    ('Coffee',31),
    ('Alex Python',120),
]
shopping_list = []
salary = input("Input your salary:")
if salary.isdigit():
    salary = int(salary)
    while True:
        for index,item in enumerate(product_list):
            #print(product_list.index(item),item)
            print(index,item)
        user_choice = input("选择要买嘛？>>>:")
        if user_choice.isdigit():
            user_choice = int(user_choice)
            if user_choice < len(product_list) and user_choice >=0:
                p_item = product_list[user_choice]
                if p_item[1] <= salary: #买的起
                    shopping_list.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]啦，还买个毛线\033[0m" % 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")
