title: How can I get from 'pyspark.sql.types.Row' all the columns/attributes name?
body: <p>I am using the Python API of Spark version 1.4.1.</p>
  
  <p>My row object looks like this :</p>
  
  <pre><code>row_info = Row(name = Tim, age = 5, is_subscribed = false)
  </code></pre>
  
  <p>How can I get as a result, a list of the object attributes ?
  Something like : <code>["name", "age", "is_subscribed"]</code></p>
