[Tkinter] how do i add a margin to a Listbox

[DT2000]

I appreciate you taking the time and I will certainly study what you have done here and I will try to implement this into my code and see what happens and I'll let you know what occurs.

I have a number of books in pdf format for python, tkinter and now wxPython but it can be difficult to decide which is best or the most useful. Each writing style varies and each has their own way to explain things, and in many case without actually explaining anything relevant or what is happening or should be happening when writing code.
I am always looking for more information or suggestions on what would be beneficial to read and things to learn for proper code structure.
