Login to NordVPN on Linux with python script

[AGreenPig]

I think I got it to work like this:

import os
import subprocess
import sys
import argparse
import time
from typing import Union

# console colors
G = '\033[92m'  # Green
W = '\033[93m'  # Warning (yellow)
R = '\033[91m'  # Red
E = '\033[0m'   # Erase (the default color)
B = '\033[34m'  # Blue

if __name__ == "__main__":
    args = read_arguments()

    # Initialize the script
    try:

I found a script on Github from behnambm that just checks if the login was successful, so I edited the script so that the connection gets tested as well. Hopes this works and helps someone.
