title: why command prompt take less time to run the python program as compare to python IDLE?
body: <p>I want to check the running time of my program by using this.</p>
  
  <pre><code>start_time = time.time()
  print(time.time() - start_time)
  </code></pre>
  
  <p>but the result was surprising in cmd it gives time of 1.2 sec but in python IDLE time is 5.12 sec.</p>
  
  <p>why it is so?</p>
