Run terminal from Python script

I am doing a work of distributed systems, in which I am using PYRO, in it I am using objeto.adapter.rebindURI() to use the same object when the server that was (dropped) is "restarted"...

I’m hoping that this re-start is from my Python program... in case I thought to call open a new window and run my server program...

Does anyone know how to do it? 'Cause I tried N times and I couldn’t. It makes the following mistake:

Traceback (most recent call last):
  File "serverApp.py", line 7, in <module>
    subprocess.Popen(cmd, stdout=subprocess.PIPE)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py",
line 710, in __init__
    errread, errwrite)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py",
line 1335, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

I tried something like this...

import subprocess

cmd = ["xterm"]

cmd.extend(['-e','bash','-c','python serverApp.py; exec $SHELL'])
python bash

  • Do you have the xterm command installed? The user running the command has access to it?

  • the idea is a script that starts a terminal and the same runs a python script ?.. or just call the terminal

If xterm is installed, the best way to ensure its execution is to pass its absolute path in the subprocess.

To find the absolute path:

~ which xterm
/usr/bin/xterm

Include this in Python Subprocess:

import subprocess
cmd = ["/usr/bin/xterm"]

Apparently Voce doesn’t have xterm installed on your machine.

I believe Voce must be trying to give a subprocess.call in cmd, the command that is executed will be:

$ xterm -e bash -c python serverApp.py; exec $SHELL

Try to run this at your command prompt and probably see the same problem.

I did not understand why Voce would run xterm before. Try to run python directly and see if the problem is not solved.

Ex:

python> subprocess.call(['python', 'serverApp.py'])
