I'm not sure if it will work, but if you add the path to the pywebview library like in the PythonLibrary.cs example, that's how you would do it.

@Proton-V Can you post the C# code and the python script you are executing? It sounds like the error is occurring on a line you omitted from your example.

import urllib.request will not work, because the request module doesn't exist in Python 2.x; it only exists in Python 3.x. This stack overflow question suggests that the equivalent Python 2.x code urllib2.urlopen.

As for your other error about not expecting type '<type 'bytes'>', I'm not really sure what might be causing that problem. Maybe you're passing in the wrong type somewhere in your Python code? This error might also be caused by the fact that you're trying to run Python 3.x code.
