title: List of dict to Pandas DF - 'NoneType' object has no attribute 'keys'
body: <p>I want to convert a list of dict into a pandas DF. One row look like this : <code>{'id': 5102, 'lat': 41.9258689, 'lng': -91.4231934}</code></p>
  
  <p>When I look at the type() I got <code>int, float, float</code></p>
  
  <p><code>temp_df = pd.DataFrame(geocode_list)</code></p>
