Call external py script from button

[hfj]

I have a script that test a local ip for connected PLC unit info. I want to call this from a button i ignition.
I am not sure where to put the script. On the button or in gateway scripts ?
Also how to get the result show up in a textbox
Here is my script:

import subprocess

pythonPath = "C:/Program Files/Python313/python.exe"
scriptPath = "c:/Python/S7_Dev_Env/listOnlineDevice.py"
param1 = "5"

result = subprocess.check_output([pythonPath, scriptPath, param1])
print result

Oh, right - system.util.execute is a 'fire-and-forget', it doesn't give you access to standard output. Try adapting this: from java.lang import ProcessBuilder, String pb = ProcessBuilder([r"C:\Users\pgriffith\AppData\Local\Microsoft\WindowsApps\python3.exe", r"C:\Users\pgriffith\Downloads\test.py"]) process = pb.start() output = String(process.getInputStream().readAllBytes()) print output (Note: This blocks until the process completes waiting on the input stream. It may or may not ever compl…

Note too - if this is vision - it does likely make more sense to have it on the gateway instead of putting a .py file on every single client. You can then write the result to a gateway tag and bind the button text to that in some fashion, or use message handlers.
