Hi, I liked the idea of creating a tkinter version and decided to try running the program, but when I do run it it gives me an error. I had a look at the code but it looks too advanced for me although I know a little about tkinter.

Error:
TypeError: getname() missing 1 required positional argument: 'event'

[Yoriz]

To make it work on line 59

    # Handles the form processing
    def getname(self, event):

remove the parameter event

    # Handles the form processing
    def getname(self):

The error is because its called by either

        self.form.bind('<Return>', self.getname)
        self.form.bind('<KP_Enter>', self.getname)

and no event attribute is passed, as event is not used you can just delete it.

You've written two versions of the game, one for the console and one with Tkinter. Essentially what you've ended up with is two entirely separate programs, with no code in common really. Seems a bit wrong, doesn't it? The rules of the game - the logic that determines which things beat which (I've referred to them as "symbols" in the past, but don't have a better name!) and the concepts of a player, etc. should be common to both programs. That means that there should be quite a bit of code you didn't have to rewrite, but share between both versions of the game. The problem is that your classes (well, there's really only one class here, Game) are tightly coupled to how you're displaying stuff. That is, your Game class knows an awful lot about Tkinter and so if you wanted to reuse it, you couldn't do so easily. The better way to design is to separate things - there should be classes that are just responsible for the "domain logic" (that is, implementing the rules, taking turns and other core concepts) and other things that are just responsible for "presentation" (displaying on a screen).

Things to learn about should you be interested: the single responsibility principle, separation of concerns, loose coupling/high cohesion.
