Introduction

JS7 can be used to execute any scripts, executables and programs including Python® scripts.

• Python® is a frequently used scripting language available for Linux, MacOS, Windows and other platforms.
• This article explains how to syntactically include Python® scripts with JS7 job scripts.

Unix

• Find examples for download (.json upload): pdScriptingPythonUnix.workflow.json

• In order to directly add Python® script code to a JS7 shell job script the recommended approach is to use a shebang like this:

  Example how use Python script code with a shebang

  #!/usr/bin/python
   
  print("Hello")
  print("world")

• Alternatively a Python® script can be executed from a file that has to be located by the executing Agent:

  Example how to run Python script code from a file

  #!/usr/bin/bash
  
  python hello.py

Windows

• Find examples for download (.json upload): pdScriptingPythonWindows.workflow.json

• In order to directly run Python® script code from a JS7 shell job script the recommended approach is to use a shebang replacement like this:

  Example how run Python® script code with a shebang replacement

  @@setlocal enabledelayedexpansion & @@findstr/v "^@@[fs].*&" "%~f0" | python.exe - & exit !errorlevel!/b&
  
  print("Hello")
  print("world")

  Explanation:

  • Credits for the shebang replacement to How to run a PowerShell script within a Windows batch file
  • If you consider this shebang replacement somewhat cryptic then add it to JS7 - Script Includes which are easily referenced from shell jobs, e.g. by using ##!include python
  • The python.exe executable is available when Python® is installed for Windows.

• Alternatively a Python® script can be executed from a file that has to be located in reach of the Agent:

  Example how to run Python® script code from a single line

  python.exe hello.py
