title: How to convert a datetime format to minutes - pandas
body: <p>I have a data frame which has a column usage_duration (which is the difference of two another columns in datetime format). It looks like below:</p>
  
  <pre><code>processid, userid, usage_duration 
  17613,root,0 days 23:41:03.000000000
  17641,root,2 days 04:05:26.000000000
  13848,acs,0 days 00:00:50.000000000
  3912,acs,0 days 06:07:38.000000000
  6156,acs,0 days 17:22:43.000000000
  </code></pre>
  
  <p>Now I wanted to convert the same into minutes. It should look like as below:</p>
  
  <pre><code>processid, userid, usage_duration_min
  17613,root,1421
  17641,root,3125
  13848,acs,0
  3912,acs,367
  6156,acs,1042
  </code></pre>
  
  <p>Can someone let me know how is it possible?</p>
  
  <p>Highly appreciate your support</p>
