Welcome to Python!  A great language for program development.

Answers might be platform-dependent (are you using WIndows, Linux, etc.).
However, the following works for me on WIndows.  You can put it in the 
startup.py file so you don't have to type it every time you start up the 
IDLE.

import os
def cls(): x=os.system("cls")

Now whenever you type
cls()
it will clear the screen and show the prompt at the top of the screen.

(The reason for the "x=" is: os.system returns a result, in this case 
0.  When you evaluate an expression in the IDE, the IDE prints the 
result.  So without the "x=" you get an extra line at the top of the 
screen containing "0".)

I am sure that some jiggery-pokery could be used so you don't have to 
type the "()".  But that's more advanced ...

Best wishes
Rob Cliffe
