The magic comment does not work.
'Nested comment found'
It seems that it does not like nested brackets in a comment.

It seems to be

(py, python code)

or

;py, python code

It calls code here:
github.com/LinuxCNC/linuxcnc/blob/2.8/sr...python_plugin.cc#L67

And multi-line python code can (probably) be passed using "\n"L www.programiz.com/python-programming/methods/built-in/exec

Though if the OP wants to do this a lot, a custom M-code might be easier.

If LinuxCNC is started in a terminal the MDI python method does write to terminal but requires a few commands:

Code:

;py,import linuxcnc
;py,s=linuxcnc.stat()
;py,s.poll()
;py,print(s.settings[3])

I don't know how to get it to appear in AXIS and I have not tried any other GUI's. I did attempt sending it to stderr but that didn't help.

Code:

;py,sys.stderr.write(f"{s.settings[3]}\n")

Thanks phil,
For output to axis add:

Code:

;py,import emccanon
;py,emccanon.MESSAGE(str(s.settings[3]))

looks like we can also pass more than one command in a single line:

Code:

;py,emccanon.MESSAGE(str(s.settings[2])),emccanon.MESSAGE(str(s.settings[3]))

MESSAGE is nice...

It even takes f strings:

Code:

;py,emccanon.MESSAGE(f"G64 P{str(s.settings[3])}  Q{str(s.settings[4])}")
