Python run a script as root and /home folder

Question

I have a problem with /home folder as root. Here is my script:

home = os.path.expanduser("~")
print home             # home is good: /home/guillaume

# gksudo
euid = os.geteuid()
if euid != 0:
    print "Running sudo.."
    args = ['gksudo', sys.executable] + sys.argv + [os.environ]
    os.execlpe('gksudo', *args)
print home            # home has changed: /root

How can I get the good /home after gksudo has run ? Thanks

Edit: I've tried

subprocess.call(['gksudo', 'script.py'])

The script is launched, but the operations inside the script are not in root

Why gksudo instead of sudo? gksudo is for graphical applications. Is that what you want?? — evading, Apr 20 '14 at 20:14
yes, it's a graphical app, I made a desktop icon in usr/share/application — Guillaume, Apr 20 '14 at 21:56

sudo sets a number of environment variables for the process; see man sudo for a list. In this case, you can use SUDO_USER:

# from under sudo
home = os.path.expanduser(os.environ["SUDO_USER"])

Thanks, This is working well. I use this to find the user. After, I add "/home/" – Guillaume Apr 21 '14 at 07:08
Do not forget '~' : `os.path.expanduser('~'+os.environ["SUDO_USER"]) ` – Liviu Oct 24 '18 at 15:40
