title: Converting a datetime column to a string column
body: <p>I'm trying to convert a datetime column back to a string in Pandas dataframe.</p>
  
  <p>the syntax I have so far is:</p>
  
  <pre><code>all_data['Order Day new'] = dt.date.strftime(all_data['Order Day new'], '%d/%m/%Y')
  </code></pre>
  
  <p>but this returns the error:</p>
  
  <p>descriptor 'strftime' requires a 'datetime.date' object but received a 'Series'.</p>
  
  <p>Can anyone tell me where I'm going wrong.</p>
