So, im creating a GUI for a book rental(library) with a database, just stuck on creating tree grid of 3 columns..to show 3 different information lists to go along it.

MY CODE:
http://gyazo.com/0247ec74f3f3c31100bac13d08510d93 <<<SELF.TREE
It's showing book title and author, but not rental duration, as shown below..when i run it.

THE ERROR:

any chance you can upload your code to http://pastebin.com/ or somewhere similar, people aren't going to type all that out to try and help.

You're using Tkinter?

From the error message it looks like you've created a table element with two columns in (Book Title, Book Author) but you are trying to access the third column (which doesn't exist).

Do you have access to the element properties when designing the GUI? Forgive me, but I'm unfamiliar with Python so I don't really know what tools you're working with.

edit: found the docs here -> http://www.tkdocs.com/tutorial/tree.html

Have you tried explicitly defining the columns when constructing the tree view? The docs also suggest that you need to pass a parent element when constructing the tree view.

Like:

tree = ttk.Treeview(root, columns=('col one', 'col two', 'col three', 'another col'))

I don't think he's shared all the of the code because there's no import for tkinter so it's hard to see exactly what else is going on.
