The ¡°subprocess.run¡± line is meant to run sometime as, well, a subprocess. This is attempting to run the 2nd script outside JMRI. It¡¯s not set up for that.
If your goal is to run a separate script file, you can use ¡°execfile(..)¡± to do that.
More generally, JMRI¡¯s scripting uses a Python derivative called Jython. The good news is that Jython works with underlying Java code well. The bad news is that it¡¯s Python 2.5, i.e. old, and doesn¡¯t have many of the nice Python packages that can do cool things.
There¡¯s been some limited work on using native Python3 for scripting, but that¡¯s really not ready for general use yet.

Could someone please advise why the following python scripts work together in RPi Thonny, but not from within PanelPro.
The script for the initiating programme, testsend.py :
import subprocess
import sys
x=678
print(x)
subprocess.run(["python3","testreceive.py", str(x)])
and this is the script for the receiving programme, testreceive.py "
import serial
import sys
if len(sys.argv)>1:
y= int(sys.argv[1])
print(1+ y)
else:
print("no argument received")
Thank you in anticipation
