LinuxCNC 2.9 Python module linuxcnc error

I testet a other version of the compensation.py
also import hal doesn't work.

Also tried this in python3 and python in the termianl.
Same result
python gives the error and python3 doesn't

Can I assume that my linuxcnc is using python 2?

what distribution are you using?

Sorry I always compile version so can't help much.
I didn't think there was a distribution that could run 2.8 and 2.9 because of the python version problem.
Hopefully someone else will chime in.
