python 将某个字段存储为列表类型

实现存储数据格式为

{
        "_index": "nested-20180815",
        "_type": "stb-iptv-montor-m-gather-apk",
        "_id": "AWU8sZboGQQbsn0rAW4J",
        "_score": 1,
        "_source": {
          "mdiNested": [
            {
              "mdiMLR": 0,
              "mdiType": "0"
            },
            {
              "mdiMLR": 0,
              "mdiType": "1"
            },
            {
              "mdiMLR": 0,
              "mdiType": "2"
            },
            {
              "mdiMLR": 0,
              "mdiType": "3"
            },
            {
              "mdiMLR": 0,
              "mdiType": "4"
            },
            {
              "mdiMLR": 0,
              "mdiType": "5"
            }
          ]
        }
      }
