title: How to clear Python Shell in IDLE
body: <p>I'm running a script that uses a module that prints a lot of things on screen and I'm running out of RAM.<br>
  I can't make the module not to write anything for now.<br>
  The Python Shell stores absolutely everything and I want to clear it.<br>
  On similar questions the only answer I could find was to write <code>os.system('cls')</code> (on Windows), but it doesn't delete anything.<br>
  Is there a way to clear the Python Shell or to limit its size?<br>
  Thanks  </p>

  <p>Edit.<br>
  Well, this question was marked as duplicate and I am asked to clarify why it isn't.<br>
  I state that <code>os.system('cls')</code> doesn't work, while the answer to the question I supoosedly duplicate is to write <code>os.system('cls')</code>.</p>
