Tkinter scrollbar for frame in a Frame - python-3.x

Question

I'm creating a dynamic container that can change between frames. In one of the frames I have a list of values that I need to scroll through because it is so long. However I cannot get the scrollbar to work with the canvas and frame set up.
i have tried using Listbox and this works but does not give me the control over the displays that I am looking for. I want to be able to configure the names of the tag and then to the right the value.

Answer 1

The canvas can't scroll things added to the canvas with grid. The most common solution is to add a frame to the canvas with create_window, and then adding the labels to the frame.

Answer 2

So i made a few changes thanks and got it working :)
Bye using pack as you sugeted it works
