How to clear the screen?

edit

Hey! I am using Sage in the Sage cloud website.

I have an infinite loop that shows a result each time it is run, only I don't want to see a billion results in my display, i'd like to clear the display everytime the loop runs. I tried the "clear" function but it does not exist. Do you know any function that would clear the screen? Or an alternate way of doing the same thing (something like a dynamic way of displaying data)

Thank you :)
