I don't quite understand this error...

"IndexError: tuple index out of range" means that you are trying to
access an element of a tuple which does not exist. In your case
int(select.curselection()[0]) raises the exception so your tuple
select.curselection() doesn't have a 0th entry which means it's empty.

HTH,
