Thank you guys for the correction.
It seems I have copied an old polygon definition in my previous email (in my
last script, I have changed odd ',' with ' ' to set couples). The issue was
that I missed double brackets. However, the importFromWkt didn't work (Being
undefined in the python bindings, I guess).
Before sending the email, I had tried ogr.CreateGeometryFromWkt(wkt) as
suggested by Even, but having missformed WKT (single brackets), it gave me
ERROR 5: OGR Error: Corrupt data. Now my problem have been solved. Thank you
all.
Best Regards,
Daniele
