title: how to get the Seconds of the time using python
body: <p>this is my code:</p>
  
  <pre><code>last_time = get_last_time()
  now = time.time() - last_time
  minute = 
  seconds = 
  print 'Next time you add blood is '+minute+':'+seconds
  </code></pre>
  
  <p>Because recovery blood every 5 minutes so only need minute and second</p>
  
  <p>thanks</p>
