[Tkinter] Database with gui

You missed something. In my code I first ask for the selection.

index = list.curselection()

If there is no selection, this returns an empty collection of some type ({} I think). Then I test if the selection is empty and return out of the function if it is.

if not index:
    return

If index is not empty then I know it is save to ask for index[0].

I think you are doing this:

index = list.curselection()[0]

This does nothing to protect against an index error, and generates an index error if you try to get "index[0]" because index is already an integer.

You did not answer my question about search. What do you think is wrong with the search function? I played around with it a bit and it appears to work very well.
