'sudo' changes enviroment variables ,such as : os.environ['HOME'], etc

import os

if __name__ == "__main__":
 
    print 'wsh'+os.environ['HOME']

    print 'wsh'+ os.path.expandvars('$HOME')

    print 'wsh'+ os.path.expanduser('~')

python envir.py
 

wsh /home/wsh
wsh /home/wsh
wsh /home/wsh

sudo  python envir.py

wsh /root
wsh /root
wsh /root

so just use:

os.getlogin()

in conclusion:

  if you want to get current user home  in linux , while you have to get 'sudo' permission. that is to say . you need sudo to start up your python script.

just use "os.getlogin()", since other commands are changed because of sudo. then use can just to get current home directory use:

'/home/'+os.getlogin()
