Clearing the screen of IDLE interactive mode using the following code:
import os
os.system("cls")
It doesn't clear the screen in Windows. Actually these two statements have no effect at all.

The cls command only works when Python is executed within a Windows terminal. In other contexts (such as IDLE), the command doesn't work.
