I haven't used the API from Python. I haven't checked PyWin32 to see if 
it already wraps that API like it wraps so many other APIs. I haven't 
Googled using "python" and "WriteConsoleOutput" to see if other packages 
may exist to do the job. But these are the things that I would do if I 
had a need to write a program like yours, since I know that the console 
does, in fact, support random access.

Off topic? It is still about doing it using Python, no?

I believe that most Unix terminal emulators, which are used for running 
shells and command lines, support cursor controls, and I believe most of 
them have a mode that emulates the DEC VT-52 terminal, one of which I 
had physical access to at the "computer lab" at the university I 
attended so many years ago. The VT-52 defined escape sequences to move 
the cursor around on the screen, providing random access. Text-based, 
screen-oriented programs such as emacs leveraged such capabilities quite 
effectively.

There may be something better today, I haven't used Unix for a dozen 
years now, and the usage at that time was database development not 
text-based graphics. I've used Linux only on my web host, and a little 
experimentation on a local machine I installed it on here, until the 
machine died, and I didn't do any text-based graphics in either of those 
circumstances either.  So probably college was the last time I used 
text-based graphics, but that was using RSTS and DECsystem 20 (forget 
the name of the OS for that machine) on VT-52 terminals. But I've noted 
with amusement that the VT-52 (and later enhanced models) are still 
supported by Unix/Linux terminal emulators and X system.

Unix abstracts that cursor motion using "curses" and I believe there are 
curses implementations for Windows as well, but I've not attempted to 
use curses from Python on either Unix or Windows.
