title: Python - Storing part of JSON response as a Comma Separated String
body: <p>I have a JSON response string that contains the results from scans from multiple antivirus sites. It looks something like - </p>
  
  <pre><code>"scans": {
    "Bkav": {
      "detected": false,
      "version": "1.3.0.9466",
      "result": null,
      "update": "20180609"
    },
    "MicroWorld-eScan": {
      "detected": true,
      "version": "14.0.297.0",
      "result": "W97M.Downloader.AIU",
      "update": "20180611"
    },
    "CMC": {
      "detected": false,
      "version": "1.1.0.977",
      "result": null,
      "update": "20180610"
    },
    "CAT-Quickheal": {
      "detected": true,
      "version": "14.00",
      "result": "X97M.Dropper.PD",
      "update": "20180611"
    },
    "McAfee": {
      "detected": true,
      "version": "6.0.6.653",
      "result": "X97M/Downloader.asi",
      "update": "20180611"
    },
  },
  "tags": {
  ...
  },
  </code></pre>
  
  <p>How can I extract all the non-empty results (all the results that are not null) from the <code>scans</code> tag in this JSON and store it into a single comma separated string in a table column of my database?</p>
  
  <p>Thanks! </p>
