购物车，一下午！！

解题思路

刚开始我是懵逼的，有点思路，但是写不出来，看了看教程跟着写最后出来了，我反复看了2遍。

product_list = [('iphone',5888),('macbook',12000),('meilv',998),('pen',5),('beizi',1),('text',25)]
shoping_list=[]

salary=input('pase inpu your money：')
if salary.isdigit():
    salary=int(salary)
    while True:
        for index,item in enumerate(product_list):
            print(index,item)
        user_choice=input('please input product list')
        if user_choice.isdigit():
            user_choice=int(user_choice)
            if user_choice < len(product_list) and user_choice>=0:
                item_p = product_list[user_choice]
                if item_p[1] <salary:
                    print("The product bice success")
                    salary = salary -item_p[1]
                    shoping_list.append(item_p)
                    print('[%s] in shopping car,your salary has \033[31;1m[%s]\033[0m'%(item_p,salary))
                else:
                    print("\033[31;1mmyour money has [%s],need addd\033[0m"%salary)
            else:
                print('product code [%s] is not exist!' %user_choice )
        elif  user_choice == 'q':
                print('-----shopping list-----')
                for p in shoping_list:
                    print(p)
                print('your salay is [%s]'%salary)
                exit()
        else:
            print('please input reallnumber')
