how to fix TypeError: format requires a mapping

[hinaimran.mehr at gmail.com]

I am pulling my hair with this problem right now,

I have the following Data structure 

    [<OldSample {u'counter_name': u'cpu_util', u'user_id': u'id', u'resource_id': u'id', u'timestamp': u'2015-06-30T15:53:55', u'counter_volume': 0.043}]

I need to make it something like this to put in EON pubnub charting libaray (see link: http://www.pubnub.com/developers/eon/chart/spline/)

    message: {
          columns: [
            ["y": 0.043, "x": "2015-06-30T15:53:55"],
            ["y": 0.045, "x": "2015-06-30T15:53:55"]
          ]

Now I have the following code 

    data = cclient.samples.list(meter_name ='cpu_util', limit=2)

result_rows = []
for row in data:
     formatted = """["y": %(counter_volume)0.3f, "x": "%(timestamp)s"]""" % (row)
     result_rows.append(formatted)
     
     print(',\n'.join(result_rows))


clean_json(data)
