title: Python - Accurate time.sleep
body: <p>I am working on a project which accurate timer is really crucial. I am working on <code>python</code> and am using <code>timer.sleep()</code> function. </p>
  
  <p>I noticed that <code>timer.sleep()</code> function will add additional delay because of the scheduling problem (refer to <a href="https://docs.python.org/2/library/time.html#time.sleep" rel="noreferrer"><code>timer.sleep</code> docs</a>). Due to that issue, the longer my program runs, the more inaccurate the timer is. </p>
  
  <p>Is there any more accurate timer/ticker to sleep the program or solution for this problem?</p>
  
  <p>Any help would be appreciated. Cheers.</p>
