How to print only the distinct part of the json after comparing 2 jsons

Question

I am comparing two jsons i am able to find the differences between the jsons. I want to print only the distinguishing part of two jsons. For example:

json1

{
  "Name": "Temperature & Pressure Measurement",
  "Id": "0x0102",
  "Channels": [
    {
      "Data": [
        {
          "Channel0": [
            {
              "Enable": 0,
              "Unit": "Celsius"
            }
          ],
          "Channel1": [
            {
              "Enable": 0,
              "Unit": "Celsius"
            }
          ],
          "Channel2": [
            {
              "Enable": 0,
              "Unit": "Celsius"
            }
          ]
        }
      ]
    }
  ],
  "Events": [
    {
      "event1": 0,
      "event2": 0
    }
  ],
  "Diagnostics": [
    {
      "diag1": 0,
      "diag2": 0
    }
  ],
  "Functions": [
    {
      "Function-1": 0
    }
  ]
}

json2:

{
  "Name": "Temperature & Pressure Measurement",
  "Id": "0x0102",
  "Channels": [
    {
      "Data": [
        {
          "Channel0": [
            {
              "Enable": 1,
              "Unit": "Celsius"
            }
          ],
          "Channel1": [
            {
              "Enable": 0,
              "Unit": "Kelvin"
            }
          ],
          "Channel2": [
            {
              "Enable": 0,
              "Unit": "Kelvin"
            }
          ]
        }
      ]
    }
  ],
  "Events": [
    {
      "event1": 0,
      "event2": 1
    }
  ],
  "Diagnostics": [
    {
      "diag1": 1,
      "diag2": 0
    }
  ],
  "Functions": [
    {
      "Function-1": 0
    }
  ]
}

{
  "Channels": [
    {
      "Data": [
        {
          "Channel0": [

  ]
}

The below is the code i am trying but unable to achieve the output any help will be appreciated!

How about:

from jsondiff import diff
diff(json1, json2)

which yields a similar output to the one you request (shows differences, if any, but in alphabetical order):

{'Channels': {0: {'Data': {0: {'Channel0': {0: {'Enable': 1}},
     'Channel1': {0: {'Unit': 'Kelvin'}},
     'Channel2': {0: {'Unit': 'Kelvin'}}}}}},
 'Diagnostics': {0: {'diag1': 1}},
 'Events': {0: {'event2': 1}}}

hope this helps.
