Setting up Anaconda to work with PSSe is a little tricky. PSSe v.34 is still a 32-bit application,therefore Anaconda has to be also a 32-bit version (for python 2.7 or python 3.4)

Anaconda install a version of python in its own directory. When running this Anaconda installed python, the path to psspy shall be appended to its sys.path. So in your scenario, above, assuming you open a CMD window or within the IDE Spyder (comes with Anaconda) showing that Anaconda's python v2.7 is running, then to connecto to PSSe v.34:

C:\ProgramData\Anaconda2>python
Python 2.7.15 |Anaconda, Inc.| (default, May  1 2018, 18:37:12) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os,sys
>>> psspypath = r"C:\Program Files (x86)\PTI\PSSE34\PSSPY27"
>>> sys.path.append(psspypath)
>>> import psse34
>>> import psspy
>>> psspy.psseinit(15000)

Similar declaration can be formed when setting Anaconda with python v.3.4 and PSSe v.34 for python v.3.4

Your code here says you are using Python 2.7 to import the psspy for Python 3.4. Of course you would get a bad magic number as a result. You either need to import the psspy for Python 2.7 or use Python 3.4 to import the psspy for Python 3.4. PSSE does not support Python 3.7.
