How to add a python application into a loop and access the loop variable within the python script?

There is no direct way of doing this but there is a simple solution. You can add a PILOT program to print out a Python file (..py) with the variables, and then import this into your Python script.

PILOT program code

PRINT LIST='a= 100' FILE="variables.py"
PRINT LIST='b= "cube"' FILE="variables.py"

Python code to import variables

from variables import *

peint(a)
print(b)

Hope this helps!

As an alternative, you can also pass the token directly as a sys.argv to your Python script.

For example, in a more general case, let's call the variable "loop_variable" defined as below (just as an example, in a Pilot program or within the Loop circle properties):

loop_variable = 12

Your Python command line could look like the below in a Pilot script direclty:

*"C:\Program Files\Python311\python.exe" "{CATALOG_DIR}\Applications\python_script.py" @loop_variable@

import sys

loop_variable = sys.argv[1]

with open("D:/some_path/Base/out_txt.txt", "w") as txt_file:
    print(loop_variable, file=txt_file)

This will print out 12 in your output text file.

Hi Ahmed

Thanks for the reply, this isn't what I was expecting but your answer provided a good tip.

I used a pilot to print a data file with the PID value, and added this file as an input in the python script

And it works!

Thanks :)
