Running multiple python scripts with subprocess python

Question

I am trying to run multiple python scripts in parallel with subprocess in a linux OS

Similar to this: Running multiple commands from multiple terminal windows from python script

Here is what I tried:

subprocess.call(['gnome-terminal', '-e', "python3 ab.py"])
subprocess.call(['gnome-terminal', '-e', "python3 bc.py"])
subprocess.call(['gnome-terminal', '-e', "python3 cd.py"])

Unfortunately, the terminal flashes in split seconds and disappears. Any reason for this? adding shell=True makes the terminal stays but does not execute the script.

Can you please edit your question to provide a minimal reproducible example? Note that subprocess.call waits for completion, so it's a) not suitable for your task and b) an indication that the failure is in what you execute not how you execute it. — MisterMiyagi

subprocess.run should work:

subprocess.Popen(['gnome-terminal', '-e', "python3", "ab.py"], shell=True)
subprocess.Popen(['gnome-terminal', '-e', "python3", "bc.py"], shell=True)
subprocess.Popen(['gnome-terminal', '-e', "python3", "cd.py"], shell=True)

Edit:

os.system("gnome-terminal -x python ab.py")

I tried with the shell=True. The terminal stays but does not run the python script. Any thoughts around this?

@JA-pythonista I edited with 4 elements in a list, did you see that edit?

Yes, I did. It opens the terminal and does nothing

Do you need to split all parts of the command line into separate strings?

subprocess.call(['gnome-terminal', '-e', "python3", "ab.py"])
