Humm, that's odd.. Well, if you run it like that in an interpreter, it does
print out return value (0), you may get rid of it by doing throw_away = os.system('clear'). In a script, os.system('clear') shouldn't leave any lines at the top, and in fact I'm using it in my mp3 player cymbaline (plug, plug!), url in my sig, and it works great.
