so pretty much what I am trying to achieve here is a Class Registration window, however I am struggling to get my data up and out of my database onto displaying all of the dogs within the training school, I have made a rough sketch of how it should be looking I have done similar stuff in the past however just struggling to remember how I would go about getting the final piece together. I know that I would have to use a method to retrieve a command for taking the data from my database and displaying it onto the tkinter, if there are any possible solutions you may think work let me know.
