Scheduling Python Scripts in Obsidian Java Scheduler

While looking into Java Job Scheduler Obsidian, I had the little problem below.
The default option for Python “com.carfey.ops.job.script.PythonJob” works well but requires you to enter the content of your script directly into the scheduler (see for a quick overview), potentially leading to a duplication of functionality and complicating the maintenance of said scripts.
Using as an example script, I tried (on a Windows machine) to use the generic “com.carfey.ops.job.script.ScriptFileJob” to call the python script but to no avail. I got it to work calling a .exe file but the different command line combinations I tried such as “python”, “python C:/Scripts/python/”, “C:/Python27/python.exe C:/Scripts/python/”, “cmd /c start python C:/Scripts/python/” and more along those lines just didn’t work, keep returning an error that “ cannot be found”.
In the end, in order to keep my python scripts out of the scheduler, I wrote a python job (using the “com.carfey.ops.job.script.PythonJob” option) to call my python script.
Python job as entered in the Obsidian scheduler (the 3 arguments and their values are defined within the scheduler as part of the job options)

import sys
sys.path.append( "C:/Scripts/python/" )
import fileFTP
fileFTP.main(arg1, arg2, arg3)

The script is structured as below to allow it to run from both the command line and from Obsidian:

import sys
def main(arg1, arg2, arg3):
       #Do FTP stuff
if __name__ == "__main__":
       main(sys.argv[1], sys.argv[2], sys.argv[3])
