[gnome-love] "import Gtk" not working

[ruwan thushara <thushararuwan88 gmail com>]

Hi
I designed ui using glade and connect it with python code. when i use "import Gtk" In the python code it gives import error in the terminal like below,
Traceback (most recent call last):
  File "test.py", line 1, in <module>
    import Gtk
ImportError: No module named Gtk

But when i use "from gi.repository import Gtk" it works as expected.

problem is why can't I just import Gtk in to the code?

Thanx
