Hi there,

If I understand your requirement correctly then we had a similar problem for some scripts we wrote.

We needed a way to set up our Python scripts so that they could run on any version of PSSE (even if there were multiples installed on the same machine.)

@Daniel_Hillier and @chip wrote a library that deals with that problem. They open sourced it here: https://github.com/danaran/pssepath. You are most welcome to use it.

Here is how you would set the script to use PSSE32

import pssepath
pssepath.add_pssepath(32)

import psspy # continue as normal

and here is for PSSEv33

import pssepath
pssepath.add_pssepath(33)

import psspy

The script should work with any PSSE version. If you find any mistakes in the code, you can post them here, or even open a ticket on github.
