Hello,
I know about those IPython commands and I searched and found several
possible solutions to clear the screen in the CPython REPL, but all are,
in my opinion, complex for a newbie.
The existence of a clear command would be simple and obvious, therefore
accessible to newbies.
Best regards,
JM

Hello,
In other interpreted programming languages the clear screen
command (whatever it is) also does not clear the session.
It just clears the screen clutter.
As I said, this would be very useful for newbies, which don't know
anything about usercustomize or sitecustomize.
Best regards,
JM

I would like to suggest adding a clear command (not

It's simple purpose would be to clear the REPL screen,
leaving the >>>
prompt at the top left of the screen.
This is something very basic but also very useful for
newbies learning
Python from the REPL.
After some trial and errors it is best to start with a
clean screen.
Clearing the screen helps clear your mind.
I'm not sure that it _is_ helpful, given that you're starting
with a
clean screen but not restarting the session (so you'll still
have all
the state from your previous work). If you want a completely fresh
start, just exit Python, clear the screen with a shell
command, and
re-enter.
The easiest way to play around with this would be to create a pure
Python clear() function in your usercustomize or
sitecustomize, and
then try it in your own workflow - see whether it annoys you
that it
doesn't change the interpreter state. Maybe it will, maybe it
won't.
