screen clear question

[jcollins]

Is there a command in Python to clear the screen? That is without writing
multiple blank lines.

Thanks.

Without knowing what 'screen' you're talking about, it's hard to say. If
you mean clearing a terminal, you can call 'tput clear' or
'/usr/bin/clear' on many UNIX systems; no idea about Windows.

import os

# windows
os.system("cls" )

# bash ( mac, linux )
os.system("clea r")

That's all I can account for.

On Windows the DOS CLS command will clear a command prompt, it
also works for CP/M and VAX terminals too. Finally I think the
curses module allows you to clear a window, including the main
window - ie the terminal screen.

In each case run CLS (or clear) via os.system()

But the bottom line is that there is no builtin command
because the mechanism is different on each platform.

I'd have said it was because the inpreter is line-oriented rather than
screen-oriented, but YMMV.

Yeah, that might be a reason as well :-)

But then the early PC GW-Basic or BASICA interpreters were line
based too but both provided a CLS command because the *programs*
that were written were usually screen based... But they ran on a
single OS so a CLS was easily possible.

I would try doing a test against the resident OS the program is running
against and set the clear command based on that.
