[Python-ideas] Suggestion: Clear screen command for the REPL

[João Matos]

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
