launch vim from python script and end script

Question

I'm a newbie in programming in general, and with python in particular ...

I'm trying to write a python script, launched from a Linux Terminal, with a 'latex' file as an argument :

my_script.py file.tex.

I wish then my_script.py to open the file.tex in vim (in the Terminal), run another compiling script and then close, leaving 'file.tex' opened in vim and the compiling script running in background.

So, I tried :

myfile = "file.tex"
subprocess.call("vim "+ myfile)
subprocess.call("Latex_compiling_commande "+myfile)

but my_script.py is still waiting for vim to close before continuing, which is exaclty what subprocess.call is supposed to do, as explained in the : official python doc.

I tried :

subprocess.Popen(["vim", myfile])

I've got an 'input/ouput error'...

Thanks in advance.

You should probably just call vim non-interactively. See example here — Gerrat

Thanks for your comment; but I wish to use vim with all its special capabilities (latex-suite plugin, mappings, ...) — Gylles

Try with:

import os
os.system("command")

For subprocess see this link

Thanks invictus for your answer. 'os.system("commad")' does the same : vim open 'file.tex'; I can edit the file, save it, do whatever I want; it's only after closing vim that my_script.py continues with the compiler command.

Thanks for the link as well; I have already checked it, but I think (as far as I understood) my question is a bit different : what 'file.tex' contains does not interact in any way with 'my_script.py'

What I really do not understand, is that : os.system("Latex_compiling_command "+ myfile) followed by os.system("vim "+myfile) works fine ... (my_script.py only ends when closing vim). Is there really any way to launch vim, then the Latex compiling command and then having my_script.py to close (leaving file.tex opened in vim in the Terminal) ?
