title: Convert integer (YYYYMMDD) to date format (mm/dd/yyyy) in python
body: <p>I have following dataframe.  </p>
  
  <pre><code>id int_date  
  1  20160228  
  2  20161231  
  3  20160618  
  4  20170123  
  5  20151124
  </code></pre>
  
  <p>How to convert above date in int format to date format of mm/dd/yyyy? Want this in particular format for further excel operations?</p>
  
  <pre><code>id int_date  
  1  02/28/2016  
  2  12/31/2016  
  3  06/18/2016
  4  01/23/2017
  5  11/24/2015
  </code></pre>
  
  <p>IS it also possible to generate third column with only Month in words? like January, February etc from int_date?</p>
  
  <p>I tried following</p>
  
  <pre><code>date = datetime(year=int(s[0:4]), month=int(s[4:6]), day=int(s[6:8]))
  </code></pre>
  
  <p>but date is in datetime object, how to put it as date in pandas DF?</p>
