i need py file to merge all json in same folder

I'd like to ask your help to merge all json files in same folder after filtering data in nested dictionary. I wanna have only results of dictionary which is marked as "ID":1 You can see json files and desired "merged.json" in the below.

----------------------json1--------------------------

{
  "results": [
    {
      "Elems": [
        {
          "Elems": [
            {
              "ligName": "Premier League",
              "nameGame": "Chelsea - Liverpool",
              "score": "2-2"
            }
          ]
        }
      ],
      "ID": 1
    },
    {
      "Elems": "bbb",
      "ID": 2,
    },
    {
      "Elems": "ccc",
      "ID": 3,
    },
    {
      "Elems": "ddd",
      "ID": 4,
    }
  ]
}

----------------------json2--------------------------

{
  "results": [
    {
      "Elems": "xxx",
      "ID": 4,
    },
    {
      "Elems": "yyy",
      "ID": 2,
    },
    {

        {
          "Elems": [

              "ligName": "Bundesliga",
              "nameGame": "Bayern - Dortmund",
              "score": "3-0"
            }
          ]
        }
      ],
      "ID": 1
    },
    {
      "Elems": "zzz",
      "ID": 3,
    }
  ]
}

          ]
