title: Read csv file including the column names as values
body: <p>I have a csv file like this:</p>
  
  <pre><code>1,2,3
  4,5,6
  7,8,9
  </code></pre>
  
  <p>I did <code>x = pd.read_csv({csv_filename})</code> and when I do <code>x.head()</code>, I only see:</p>
  
  <pre><code>4,5,6
  7,8,9
  </code></pre>
  
  <p>where <code>1,2,3</code> are set as column names.</p>
  
  <p>I would like to see:</p>
  
  <pre><code>1,2,3
  4,5,6
  7,8,9
  </code></pre>
  
  <p>Does anyone know how to achieve this?</p>
