Messages for api STRT_2 No network data in memory (005354) I get the following error. I think it's because the code is different from version 33 and version 35 of Python code.

Check the error code from psspy.case.

The code works fine (I use the savnw files) in v.35 with python 3.9, v.34 with python v.3.9.

Almost every psspy function can return an error code as explained in the API manual, like:

ier = psspy.case(...)

where ier = 0 means "No error". Did the "case" function return 0 (suggested check by @perolofl)?

A programming trick to stop the run at a point when an error occurs: put all python code of interest within a single for loop, and exit the loop when and error occurs:

for k in range(1):
    ier = psspy.case(path+'\B02_CASE01_P100_QZ000_SCR20_XR20.sav') 
    if ier: break
    ier = psspy.fdns([0,0,0,1,0,0,99,0])
    if ier: break
      ...

I want to apply PSS/E 33 version of Python code to PSS/E 35 version, but I get an error. How do I fix the code?
