Hello Everyone! I have created a python file where I have written some sys.argv arguments and in a javascript file I have created a node and exported to node-red, using this js file I pass in the arguments to the python script. I want to directly pass the arguments to the python file using node-red how is that possible?

I am trying to connect to a controller and request some data from it. I am providing some images for your reference. Thank You!!

Why all the hassle with the python script for some UDP communication.  
Isn't it easier to use the NR UDP nodes?
