Run an app in a standalone terminal and wait until it's closed

[glestwid]

I would like to run an app in a separated terminal from my Python3 script and make the script wait until I close the terminal. I tried to run this code:

result = subprocess.run(["xfce4-terminal", "-e", "./etherdump.sh"], capture_output=True)

but it goes further w/o waiting of closing the xfce4-terminal. How can I make it wait the app closed?

What happens if you run xfce4-terminal from the command line?

subprocess.run() DOES wait for the command to finish. So my guess is that the terminal starts up a new process, then immediately exits. Is there a reason you can't just run the "etherdump.sh" script directly?

I had to run the "etherdump.sh" from my python-ел app by button click, then wait and close the script after some time of its work at the moment I could recognize only visually. After finishing the script I had to go further with its results in the python app. That's why I needed to implement such run in a standalone terminal window. Ultimately I resolved the issue with replacement of "xfce4-terminal" for "xterm".
