Command line execution in different folder

Question

I\'m calling a command line program in python using the os.system(command) call.

How can I call this command passing a different folder for execution? T

Here, I made a little function to change the path you're working on :

import os
def make_path(r_path):  
    ack = 1
    try:
        root = os.path.dirname(__file__)
        rel_path = os.path.join("..", r_path)

        abs_path = os.path.join(root, rel_path)
        os.chdir(abs_path)
        ack = 0
    except Exception as details:
        print('problem to get to the path '+r_path+' (0001) : ' + str(details))
    return ack

So here, r_path is the relative path you want to go to. I added ".." to the path.join() methode so, if you're in a folder and want to exit it before searching for your path, it does it automatically. So, if your relative directory looks like this :

-path_to_reach
    -a_random_file.txt
-your_current_folder
    -your_program.py

you can do those lines to go inside the path_to_reach and make your command, in exemple :

command = ls
make_path('path_to_reach/')
os.system(command)

This command would not be useful, but you see the idea!
