Best python module for Oracle, but portable to other RDBMSes

Thanks Olivier and Jonathan.

Do either of you, or anyone else, know of a good open source data
modeling / ER-diagram / CASE tools? I'd like to be able to build
relatively simple schemas in one open source tool and be able to create
a database on different platforms as needed (e.g. MySQL, PostgreSQL,
Oracle, etc).

Just wondering what's out there.

Thanks.
