I'm using Blender 2.79 with Python 3.6 on Linux. I'm trying to learn to set up a multi-module add-on and this is my reference: Multi-file Add-on Tutorial
Unfortunately I am finding in cases the ".append()" or ".values()" code is failing. I am thinking perhaps this is because I am using Python 3.6 and perhaps the tutorial uses Python 2 (I'm completely new to Python as of a few days ago). Is there a Python version mismatch causing the errors?
If so, is there a recommended multi-file/multi-module add-on tutorial around using Python 3.6?
