Python 32 and Python 64 bit

[Nx]

Suse Linux 9.2 64
Python 2.3 64 bit
Python 2.4 32 bit

My question is :

I have a python prog which is installed for python 2.3
but I need some variables filled with data, which I only can
get with running a python prog via python 2.4
(data is comming from a firebird database server via kinterbase
Â* all needs to be 32 bit).

How do I call python 2.4 from within python 2.3 and
load my variables with the data from the python 2.4 run ?
