  from gi.repository import Gtk
  
  win = Gtk.Window()
  win.connect("delete-event", Gtk.main_quit)
  win.show_all()
  Gtk.main()
  </code></pre>
  
  <p>after give chmod +x for this python file can run with this command "./test.py" 
  and if i try to run with python (with out use #! ....) and type this command "$python test.py" that run and work without any problem but when i type this command "$python3 test.py" i get this error :</p>

    File "test.py", line 2, in &lt;module&gt;
      from gi.repository import Gtk
  ImportError: No module named 'gi'
  </code></pre>
