tkinter Toolbox 2021D 72dpi 040521

This version, 2021D, started with the decision that it would continue to be densely packed information but would be developed with no page limit – we would cover the subject.  It is in three sections, basic tkinter, tkinter with the addition of Ttk, and miscellaneous.  It adds a “get started intro”, expanded functional text. tables for the effects of Ttk, explanations of the supporting modules, and of course corrections to errors in the last version.  It took just a smidge over 15 pages to cover the subject. So the last of the back page is devoted to a sort of an alternate solution – a GUI module that is a wrapper to tkinter called PySimpleGUI which is a generational improvement in ease of use, time to learn, time to construct, length and clarity of code.  If that is not the definition of “Pythonic” I can’t imagine what it would be.
