        Id: 2,
        Name: "体验资源池2",
        ProviderId: "c87e2267-1001-4c70-bb2a-ab41f3b81aa3",
        UserId: "",
        UserName: "",
        Env: "2",
        CreateTime: "2017-02-15T11:28:12+08:00",
        UpdateTime: "2018-07-04T10:41:57+08:00",
        ExpireDuration: 32486400,
        Description: "体验2",
        IsDefault: 0,
        IsFree: 0,
        Type: 1,
        Ecs: "3"
        },
        {
        Id: 52,
        Name: "test1",
        ProviderId: "158678b8-6099-427b-a3a3-f7f26e1bf7a0",
        UserId: "",
        UserName: "",
        Env: "1",
        CreateTime: "2017-04-07T14:57:33+08:00",
        UpdateTime: "2017-04-07T14:57:33+08:00",
        ExpireDuration: 86400,
        Description: "",
        IsDefault: 0,
        IsFree: 0,
        Type: 1,

        }
]
获取关键字“ProviderId”这段怎么获取？？？？
使用以下方法只能获取到第一个
str2 = "ProviderId"
print(pool_list.find(str2)后面的获取不到。

当然得用for循环遍历列表
