Any way to clear python's IDLE window?

I know there's a similar topic about python console, but I do not know if they are the same. I tried system("clear") and it didn't work here.

How do I clear python's IDLE window?

The "cls" and "clear" are commands which will clear a terminal (ie a DOS prompt, or terminal window). From your screenshot, you are using the shell within IDLE, which won't be affected by such things. Unfortunately, I don't think there is a way to clear the screen in IDLE. The best you could do is to scroll the screen down lots of lines, eg:

print ("\n" * 100)

Though you could put this in a function:

def cls(): print ("\n" * 100)

And then call it when needed as cls()

os.system('clear') works on linux. If you are running windows try os.system('CLS') instead.

You need to import os first like this:

import os

Most of the answers, here do clearing the DOS prompt screen, with clearing commands, which is not the question. Other answers here, were printing blank lines to show a clearing effect of the screen.

The simplest answer of this question is

It is not possible to clear python IDLE shell without some external module integration. If you really want to get a blank pure fresh shell just close the previous shell and run it again

ctrl + L clears the screen on Ubuntu Linux.
