Is it possible to print a string at a certain screen position inside IDLE?

问题

EDIT: I just discovered that it's possible to obtain a similar behaviour by using the standard library "curses". There are some demonstrations about how it works here and there, for example on YouTube: http://www.youtube.com/watch?v=Bj-H9uPEa5U

It's a strange and silly question I know, but I'm curious because I don't know that much about python and how it works. From the terminal or when you use IDLE, is there any way to print a string at a certain screen position?

I'll try to explain this better: Do you remember the old days when you used to make small programs in Basic, maybe on a Commodore 64, Apple II or ZX Spectrum? During that days if you wanted to print a string at a certain position you used to write something like this:

10 LOCATE 30, 40 : PRINT "hello world"

I'm just curious to know if there's any way to tell python to print a string at a certain position, and if there's a way to know how many columns and how many rows can be actually displayed inside the IDLE window.

Since English is not my native language I've also made a mockup draw, to explain this concept a little bit better :-)

Thank you.

I don't know if this works on IDLE, but it does in any normal terminal:

import sys
def print_there(x, y, text):
     sys.stdout.write("\x1b7\x1b[%d;%df%s\x1b8" % (x, y, text))
     sys.stdout.flush()

This uses Ansi-Escape Sequences
