It is not at all clear what you want the function to do.
Can you describe what the user would do to activate this
function and what the result would be?

If you just want the index of the selected item(or items
since there could be more than one) within the list
then the Listbox has a method for that, you don't need
to write a function.

eg:

class MyGUI(Frame):
   def __init__(self,parent):
      .... # build GUI
      self.myListbox = tkinter.Listbox(....)
      ...
      tkinter.Button(self, text="OK", command=self.handle_OK_button)
      ...

   def handle_OK_Button(self):
       selected = self.myListbox.curselection()
       for index in selected:
           item = self.myListbox.get(index)
           ... # process item here.


But unless you explain more about what the function is
supposed to do we can't really help. It may seem obvious
to you but it isn't to us!
