Printing string at specific position on terminal - not showing

[__Mathieu__]

Hello,

I am studying Python and currently working on matrix.
I want to print an empty matrix and pointing the position of each matrix element by a dot.

When I launch the script I get arrow pointing the left of my terminal screen.
I guess the "dot" are on the left.

←[1;1H.
←[1;18H.
←[1;7H.
←[1;24H.
←[1;12H+
←[1;30H=

What am I missing ?
Is it my code which is wrong ?

Stackoverflow link with issue + code detailled

Please, could someone help me ?
I am blocked.

Thank you in advance

Best Regards

Mathieu
