Hello Node-Red Community. I am currently working with a Robot linked to RoboDk Software and I have a Python Script whose output are the values from the Robot (like Axis-Position, Torque, etc). Now I want this output to be shown in Node-Red. I have tried something like this before and it worked, but this time, It is creating a problem

What problem?

Are you using an exec node to do it? That is the way I would do it.

Typically yes. But with the execition node, it is not working. Would it be okay, if i send the python script here so you can maybe have a look at it?

What do you mean by not working?

Add debug nodes (showing the full message) to all outputs of the exec node and see what you get.

Well, when I am executing the script in cmd, it works. But when I am doing the same in my execution node, I can't see any output on the debug window

Here's a very simple flow (an adder) to test running a Python script on a Raspberry Pi.  
Sorry - I have no experience of RoboDK.  
It passes two arguments to the Python script which returns a result.

 ![thurs_python_a](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/9/e/9ed9bf7ebe352b920d6f02a38a41f793652b2c5d.png)

```

```auto
#!/usr/bin/env python3
import sys

a = int(sys.argv[1])
b = int(sys.argv[2])
# c = int(sys.argv[3])
result = a * b
print('Result of multiplying ',a," by ",b, " is ",result)
print(result)

```

This is what appears in the Debug node.

I appreciate for your Input. A Python Script has already worked on node red, It is only this time that I am using a module from Robodk in Python which i believe is causing the trouble. It would be helpful if I shared the python script.

Have you added debug nodes to all three outputs?

Does a pid value appear under the node when you run it?

Please answer all questions

1. Does the script terminate (the PID will disappear). If the script continues running, make sure that you have 'Output while the command is running selected - spawn mode' selected in the Exec node.

2. Have you added debug nodes to all three outputs?

3. Is there any output on any of the debug nodes?

Really sorry - I do not time to wade through your Python script.

Did you try my simple 'adder' script because if that works, with your RoboDK, then that would illiminate one part of the jigsaw puzzle?

Thank you for your help. I have already executed a python script on node red, where I am calling the values from my influxdb database. In this instance, The values that i want node red to display on the debug screen is not really happening through the execution node. Meanwhile using the cmd, It is working just fine.

1. The script does not terminate, as the values keep on coming from the robot.
2. I will add the debug nodes now to check is I can see anything
3. I will get back to you on this .

Thank you for your Input

Nope, not helpful.  
How did you copy and paste that?  
A python comment such as

`# Documentation: [RoboDK API - RoboDK Documentation](https://robodk.com/doc/en/RoboDK-API.html)`  
appears in the forum as an Hi header:

# This is an H1 header

And indented python text just posted in the forum loses it's indentation, making it invalid python code.

The solution to these difficulties is to wrap **the entire script** between triple backtick lines like this

You seem to have managed this for fragments of your script.

Your topic title is "Read the output of a Python script..."  
How does this equate with "the values keep on coming from the robot" and "I can't see any output on the debug window"?

I would put a bet on it being that spawn mode output had not been selected.

Sorry for my late reply. The problem was sorted thanks to Colin's suggestion about the spawn mode.
