Utilize functions to provide a way to clear Python's integrated development environment (IDLE) window. In your initial post, provide the function for achieving this task and explain the process of clearing the IDLE window. Discuss some challenges that you faced in accomplishing this task.

Please help.... I have tried so many things like these two below.

clear = lambda:os.system("cls")

def cls():

print(' ' * 50)

I cannot seem to find something that works to clear the scree. I am using python 3.8.5 shell in IDLE. As far as challenges I am facing well that I cannot find how to clear the screen, and that I am kind of lost as to why use 'clear' or 'cls'.
