body: <p>I have a data in this format:</p>
  
  <pre><code>{'data': [{'ask': 8880.6,
             'bid': 8866.1,
             'high': '9888.8',
             'last': '8893.2',
             'low': '7500',
             'pair': 'BTC:USD',
             'timestamp': '1517580261',
             'volume': '4959.57424274',
             'volume30d': '55778.24679612'},
            {'ask': 979.98,
             'bid': 965.05,
             'high': '1187.57',
             'last': '965.02',

             'volume30d': '306271.85175700'},
            {'ask': 1177.99,
             'bid': 1118.03,
             'high': '1406.67',
             'last': '1179.17',
             'low': '970',
             'pair': 'BCH:USD',
             'timestamp': '1517580261',
             'volume': '1313.36298096',
             'volume30d': '26008.22405422'}]
  </code></pre>
  
  <p>what i want is is only the first values of "ask, bid, high, last, low, pair, timestamp, volume, volume30d" dynamically, because the data updates and I want the code to provide these values dynamically.</p>
