How to find the location of the configuration file passed as argument to Python script?

Question

I think the title of the question is descriptive enough.

How can one find the location of the configuration file which is passed as an argument to a python script.

I would like to create a backup of the config file but copying it to another location.

Can post and example of how you supply this argument to your script on the command line? — Igor

You can join current working folder to the argument path to get an absolute path.

import os
import sys

if len(sys.argv) > 1:
    full_path = os.path.join(os.getcwd(), sys.argv[1])
    print(full_path)

but this will not work for a config file which is not in the same directory with the script, will it?

It will. If you provide an absolute path, the result is the absolute path, whereas if you provide a relative path, it is relative to the current folder.
