Syntax Error for use of 'nonlocal'

[curzon01]

That's nothing to worry about.

The error occurs when decode-config is started with an outdated Python V2 (has reached EOL 01 Jan 2020), but decode-config is written for Python V3.

The script expects the command python starts a V3. This should also be the operating system default because V2 should be an exception due to EOL.

If you have both versions installed, you should configure your system so that the command python starts a python V3, not V2 and V2 only starts when python2 is explicitly entered or simnply uninstall V2. How this works, depends on your OS, there is no general answer.

[curzon01]

Your first call started python2 from somewhere, nonlocal is a python3 keyword, this error occurs if you try to run the script using python2

Your python installation seems to be a mix of python2 and python3 - check and cleanup

[curzon01]

Can not be reproduce

It looks like a local mixup of outdated script and/or mix of python env.

Ah!
Yes, I have both.

ubuntu@ubuntu:~/tasmota/configs$ python -V
Python 2.7.18
ubuntu@ubuntu:~/tasmota/configs$ python3 -V
Python 3.8.10

Changed here and it works now:

ubuntu@ubuntu:~/tasmota/configs/decode-config-development$ more decode-config.py    
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from __future__ import print_function

ubuntu@ubuntu:~/tasmota/configs/decode-config-development$ ./decode-config.py -s $deviceip  -g System | jq

I had this same problem, fixed it with the change to "python3" inside the file.

I don't know much about Python environments, but I gather this is not a bug but a configuration problem? Should I worry? How should I fix my setup? I only use it for decode-config, on this computer.

Thanks
