title: Python - change JSON values and pretty print
body: <p>How to change Values in JSON by using Python in any of the nodes (value1, value2, value3, value4, value5, value6, value7):</p>
  
  <pre><code>{
      "key1": "value1",
      "level2": {
          "key2": "value2",
          "key3": "value3",
          "level3": [
              {
                  "key4": "value4",
                  "level5": [
                      {
                          "key5": "value5",
                          "key6": "value6"
                      }
                  ],
                  "key7": "value7"
              }
          ]
      }
  }
  </code></pre>
  
  <p>After changing e.g. Value6 with some other value - I would like to print that new JSON in a nice print format (same as above).</p>
  
  <p>Thanks.</p>
