It clears the screen by scrolling all the characters out of sight at the top of the terminal window. So the screen is blank, but not cleared in the sense that I mean it. The behavior I want is for the display to be effectively "erased" and ready to receive the next wave of data -- like you would do in a UI -- which is what I'm used to working with, which is why this is mildly frustrating, and at least 1/3 of why I sound like an idiot with this question.
Anyway, I don't want it to scroll, just, in essense "refresh". As a total Python noob, my approach has been os.system("clear") ,then print "something". -- http://mail.python.org/mailman/listinfo/python-list
