Until now I have executed Python scripts using an exec node in this way:

> python -u /home/pi/....../script.py

and everything works great.  
I have a situation now where I need to execute a Python2 script with a payload. In terminal I execute it in this way and it works fine: python2 ./sendsigfox1.py 123abc  
The script send the message 123abc on sigfox uplink.

How can I do that with a nodered exec node passing the payload (123abc ) as an argument to the script?  
I would appreciate some help. Being an hobbyist,..... at time is difficult.  
Thank you

Should work - make sure you add a space at the end of the command line after .py

And you tick the Append msg.payload

in general for python I would add the -u flag as well to ensure any output is unbuffered and sent back immediately... eg `python2 -u /path...`
