asset_all=0
i1 = input("请输入总资产：")
asset_all=int(i1)

    {"name":"电脑","price":200},
    {"name":"手机","price":10},
    {"name":"鼠标","price":20}
]

for i in goods:
    print(i["name"],i["price"])

    if i2.lower() == "y":
        break
    for item in goods:
        if item["name"]==i2:
            if i2 in car_list.keys():
                car_list[i2]["num"]+=1
            else:
                car_list[i2]={"num": 1,"single_price":item["price"]}

print(car_list)

for k,v in car_list.items():
   count=v["num"]
   s_price=v["single_price"]
   all_sum = count*s_price+all_sum
