I took a look at the script and it seems to be fine. Double checked myself by running it with python 2 and 3. Everything seems to be running without syntax error. What version of python and have you made any modifications to the script there?
Thank you… So I was trying to run it under WSL on Win10. I changed to a dedicated Linux drive and all works fine. Both have Python3 installed. I think my Linux drive is going to be getting more use…
