I have PsseExplore34, and python 2.7.13, and my PSSE path is

C:\Program Files (x86)\PTI\PSSEXplore34\PSSBIN

and psspy.pyc is there

C:\Program Files (x86)\PTI\PSSEXplore34\PSSPY34

and C:\Program Files (x86)\PTI\PSSEXplore34\PSSPY27

this is part of my code that import psse

import os,sys

PSSE_PATH = r'C:\Program Files (x86)\PTI\PSSEXplore34\PSSBIN'

sys.path.append(PSSE_PATH)

os.environ['PATH'] += ';' + PSSE_PATH

import psspy

,but whenever I run it I got this error message ImportError: No module named psspy I put this line import psse34 before impoert psspy, but it still does not work.

what should I do?

If you're on a newer version of PSS products, you can do import psse33 or import psse34 instead of the explicit extra path adding.

Do a quick sanity check. Open PSSE explore, and then type

import psspy

into the Python command line. If you don't get an error message in the Output Bar, then there's some problem linking everything up externally.

Thanks for the help. My problem is solved as following: sys_path_PSSE=r'C:\Program Files (x86)\PTI\PSSEXplore34\PSSPY27' sys.path.append(sys_path_PSSE) os_path_PSSE=r'C:\Program Files (x86)\PTI\PSSEXplore34\PSSBIN' os.environ['PATH'] += ';' + os_path_PSSE
