Only if you help us to help you. I don't know MEL and don't know how to
read the following:
> float $pos[3] = `xform -q -rp $obj`;
> if ($pos[0] != 0 || $pos[1] != 0 || $pos[2] != 0)
and chances are nobody else here does either. Can you explain in words
what it does? If you're getting an error, best to show us the code you
tried and the FULL error you are getting (copy and paste it please, as
text, don't post a screenshot).
I'm going to take a wild guess that the code means something like:
pos = an array of four values
if pos[0] != 0 or pos[1] != 0 or pos[2] != 0 then:
call an external program xform with arguments -q -rp obj
convert the result to a floating point value
set pos[3] to that number
which would be something similar to:
import subprocess
if any(pos[:3]):
output = subprocess.check_output(['xform', '-q', '-rp', obj])
pos[3] = float(output)
