Python 3 - Connecting with JDBC
As I can not delete this answer, I will edit it:
Way back when, I created a Python3-port of JayDeBeApi. But as the other answer points out, the official JayDeBeApi now supports Python3 as well.
Starting from version 0.2 the official JayDeBeApi now supports Python 3 as well. It is still backwards compatible with Python 2 and Jython.
