Well, just try :
os.system('open -a X11.app; cd ~/; printenv; DISPLAY=:0.0; export
DISPLAY; echo %s | sudo -S %s; sudo -k' % (password, binpath) )
The reason is, you have 2 "%s" in yor string, thus after the "%"
operator, you need a 2-element tuple ! If you have either more or less
element, you'll get a TypeError ! In your code above you put a single
element ...
