title: speed python script on command line vs launched in IDLE shell
body: <p>I noticed several times that a simple python script (with some straightforward algebraic computation in a loop) runs considerably faster (up to a factor 6) when launched on a shell command line as compared to a run via IDLE's shell. There is nothing fancy going on in the script. I only print a loop variable to visually follow progress in the loop.</p>
  
  <p>Surely just this print statement cannot be the reason for the speed loss in IDLE, or can it ?</p>
  
  <p>Can someone explain me why this is ?</p>
