Can I detect if my code is running on cPython or Jython?

django, jython, python

Solution

if you're running Jython

import platform
platform.system()

return 'Java' here has some discussion, hope this helps.

Problem

I'm working on a small django project that will be deployed in a servlet container later. But development is much faster if I work with cPython instead of Jython. So what I want to do is test if my code is running on cPython or Jython in my settiings.py so I can tell it to use the appropriate db driver (postgresql_psycopg2 or doj.backends.zxjdbc.postgresql). Is there a simple way to do this?
