Python Top Level JSON Index
<p>I have the following JSON file from an API I am calling:</p>

<pre><code>{
  "14500": [
    {
      "5": {
        "versionName": "VersionOne",
        "expand": "executionSummaries",
        "name": "Regression",
        "projectId": 15006,
        "startDate": "",
        "executionSummaries": {
          "executionSummary": []
        }
      },
      "7": {
        "versionName": "VersionOne",
        "expand": "executionSummaries",
        "versionId": 14500,
        "projectId": 15006,
        "startDate": "19/Sep/16",
        "executionSummaries": {
          "executionSummary": []
        }
      },
      "-1": {
        "versionName": "VersionOne",
        "expand": "executionSummaries",
        "name": "Ad hoc",
        "modifiedBy": "",
        "projectId": 15006,
        "startDate": "",
        "executionSummaries": {
          "executionSummary": []
        }
      },
      "recordsCount": 3
    }
  ],
  "14501": [
    {
      "-1": {
        "versionName": "Version 2",
        "expand": "executionSummaries",
        "projectId": 15006,
        "startDate": "",
        "executionSummaries": {
          "executionSummary": []
        }
      },
      "recordsCount": 1
    }
  ],
}
</code></pre>

<p>I need to iterate through the top level, and the next level (ex. "14500", and "5", "7", etc..) to find keys and values. So for instance I need to search through the entire JSON file to find the name that matches "Regression" and locate that set of datas values for "ProjectID" and possibly other strings. I had previously done this by using data["level1"][0]["level2"] etc., but in this case the numbers will never be the same so I don't know how to call them. I wrote the following after looking through some posts on here, but it only works for one level, not the next level down in JSON.</p>

<pre><code>request = requests.get(getCyclesURL, headers=headers)
requestData = json.loads(request.text)
requestDataKeys = requestData.keys

for k in requestDataKeys():
    dictionaryIDs = requestData[k]
    for m in requestDataKeys:
        newDictionaryIDs = requestData[k][m]
        for dict in newDictionaryIDs:
            if dict['versionName'] == versionName:
                versionID = dict['versionID']
                print '%s: %s'%(versionName, versionID)
</code></pre>

<p>Here is a partial script tailored to your exact input. If it finds <code>name: regression</code> at the appropriate level, it prints a few of the related values.</p>

<pre><code>for k, list_of_dicts in requestData.items():
    for d in list_of_dicts:
        for k, v in d.items():
            if isinstance(v, dict) and v.get('name') == "Regression":
                print '%s: %s %s'%(v.get('projectId'),
                                   v.get('versionName'),
                                   v.get('versionId'))
</code></pre>
