You have a function inside a function.  In Python, methods are functions 
bound to classes.

|            Method1
|                        Lista=a,b,c,d.

That makes a tuple, not a list.  Do
    lista = [a,b,c,d]
to make a list that you can modify inside an inner function using item or 
slice assignment or modify-in-place methods

|                        Lb=listbox
|                        Method2
|                                   Lista=e,f,g..   -->error!

         lista[:] = [e,f,g]
will replace the contents of lista

Good luck.
