Hello Massimo, How is it going? As I promised we have uploaded the new CUBRID Python API Doc. You can download it from http://www.cubrid.org/python_programming#manual or view it online at ftp://ftp.cubrid.org/CUBRID_Docs/Drivers/Python/8.4.0/index.html.
The documentation is prepared by Epydoc. I also wonder if anyone has some preferences regarding the documentation generator. I would be glad to know.
