Open python program within a different command-line-interface(CLI)?

I need a python script that opens another CLI and run it in there. E.g.

python C:\Python27\Scripts\script.py test
python /path/to/script_folder/script.py test

I need to support both Unix and Windows.

Any suggestions?

After much deliberation, reading this question and others, I found the solution, had my "man am I dumb" moment, and in the end, this will do the trick:

command = r'start cmd.exe python "' + <script> + r'" [args]'
os.system(command)

The keyword there is "start." It does magic that basically tells Windows that the file to execute has no relation to the actual caller, and viola, you have a new console.

I'm not sure about Unix, but I assume it'd be similar, using gnome-terminal somehow.

If I understand your question correctly, you want to:

  1. launch a python script
  2. This script should itself launch a new terminal window
  3. In this new terminal, another python script should be run

Depending on whether point 3 must then leave the terminal window open, solutions can be very different.

If you don't need the window open, just go for os.system or subprocess. If you are only running a python script, you might get away with just specifying "python" as the executable, hence being cross-platform.

If you do need the window open, you'll have to launch the specific shell+terminal, which is OS-specific (cmd.exe in Windows; in the unix world, /bin/sh, /bin/bash or whatever else, probably wrapped by xterm).

But to be honest, unless there's some very specific requirement to have a completely different terminal session open, what you should do is just import the second module and run it from the first, or read it in memory and then use exec.

If you are you looking for running an interactive console in your script, then I'd use something like this:

import code
console = code.InteractiveConsole()
console.interact()

You can find more information in the code module documentation. In particular, you might be interested in the runcode and runsource methods.

If you are looking for running a script and continue after the script execution in a python shell, then I'd use something like this:

$ python -i <path_to_script>
