I took another look at what you are trying to do, and if I wanted to count
the number of times the button was pressed in the same way you are trying I
would do something like this instead:

You have other issues at play here, but to answer your question from below:
You are calling the method "reveal" prior to creating the global object

You can try moving:

It's not hard. You have two choices: each character of the string
represents a bit, and should be either a "0" or a "1" (anything else is
an error). In which case its numeric value is

I will use your enums declaration and the range part to use as keys for
enums.
And I will raise a KeyError in toString() to handle invalid littera

Hello Steven,
(1) slots = [] doesn't do anything special. You have misspelled
__slots__.
Yes sorry my mistake :-[
(2) Classes don't become read only just because you add __slots__ to

wish to do that?
I know this is ugly
