title: Removing header column from pandas dataframe
body: <p>I have the foll. dataframe:</p>
  
  <p>df</p>
  
  <pre><code>   A   B
  0  23  12
  1  21  44
  2  98  21
  </code></pre>
  
  <p>How do I remove the column names <code>A</code> and <code>B</code> from this dataframe? One way might be to write it into a csv file and then read it in specifying header=None. is there a way to do that without writing out to csv and re-reading?</p>
