The idea of adding some kind of clear_screen() function in the os or shutil module was discussed extensively on python-ideas a few months ago:

I would not want to clear the terminal scrollback buffer, in which case the implementation in Windows would need to use the console API and/or VT sequences instead of the CMD shell's CLS command.
