It says stash is not defined. That means there is no
variable named stash visible to Python inside the
init method of BJ_Game.

The only stash defined is in the main function.
variables defined inside a function (including main()
are *only* visible within that function, nowhere else.

But you have lots of missing names all over.
I suggest you review yuour code before trying
to run it, otherwise you will be seeing a lot of
these error messages.

You will fund information about naming and scope
in the "Whats in a name?" topic of my tutorial.

HTH,
