I have a python script ('script #1') that runs in a Windows CMD window all day long. The script runs a pynput keyboard listener, and I use this to execute a defined function in the script via a hotkey.

Can I use this same script to add/listen for a hotkey and then launch a different virtual environment and execute a separate python file ('script #2')? Any pointers on how this could be implemented?

Or should I instead add a keyboard listener to script #2 and then dump everything except the import statements of script #2 inside a def functionName block, and then run this second listener script in a separate CMD window? Seems kind of inefficient to do this way, especially as I'd ideally like to have a number of python scripts execute via hotkey.

  • May I know what does your script do, as in what's in your function? do you really need a new virtual environment or you want both scripts to be running on the same environment? I would highly suggest for you to explore multithreading in python if you want to run few tasks at a time, instead of executing different scripts for it. Commented Nov 23, 2022 at 2:40
  • @SinHanJinn Script #1 has a keyboard listener, and I use it to copy text, manipulate it and paste into a particular app. I run this as needed, usually multiple times/day. Script #2 uses a different virtual environment than Script #1, though I could install the necessary packages to Script #1's virtual env. Script #2 gets run a few times/day, and I currently run it from VS Code; just looking for a more convenient method of executing the script than having to switch to VS Code window, selecting file and running it.

  • Since you already have script 1 running to detect your keyboard inputs, I think it's redundant for script 2 to do the same. You could try to call script 2 from script 1 under it's own environment. See if this method helps >> stackoverflow.com/a/63064925/12128167 Commented Nov 29, 2022 at 3:51
  • So I tried including this in script 1 (function 2 is activated by a hotkey that script 1 is listening for): def function_2():, subprocess.run(["D:\coding_projects\myProj1\proj_env\Scripts\python.exe", "-c", "print('test using venv python')"]), this works fine. But when I change definition of function 2 to: subprocess.run(["D:\coding_projects\myProj1\proj_env\Scripts\python.exe", "D:\coding_projects\myProj1\test_script.py"]), I get a configparser error and I can see the configparser.py that is called is from system installation of Python, not the venv python.

  • I can't debug without seeing script 2. Are you using configparser() function? Commented Dec 5, 2022 at 1:20
