Override on terminal

[fivestars]

Hi there.

I'm computer science student at the end of my degree. I'm new about
python.

I've a question for all of you.

Do you know how to write, from python code, on a unix(linux) terminal
on specified coordinates?
And also: is it possible to override, from python code, something on a
unix(linux) terminal?

I would have a suggestion that won't use files.

I hope that i've been clear.

Thanks,

      Mattia
