Hello, I meet a problem for Python in PowerFactory.
When I want to import powerfactory, there is always a problem, saying no module named 'powerfactory'.
How could I modify it? thank you!

Hello, you can solver this problem using the next code:

import os
os.environ["PATH"]=r"C:\Program Files (x86)\DIgSILENT\PowerFactory 15.1"+os.environ["PATH"]

import sys
sys.path.append(r"C:\Program Files (x86)\DIgSILENT\PowerFactory 15.1\python")

import powerfactory as pf

I have solved this problem. I found the version of Python and PowerFactory should keep the same. Then it works.
But when I want to generate an event in a generation, a code always shows error below:
evt1[0].p_target = gens[2]
The error is 'DataObject' object is not subscriptable.
How could I modify it? Thank you!
