It's not a bug. In Python classes and global variables share the same

Don't you think you should learn a bit more about how Python manages
objects and namespaces before going around calling things bugs?

Just by a brief look at your code snippet there are a few things that I
would point out, stylistically, that you may consider changing in your
code as they are generally not considered pythonic:
* As already mentioned the state class is best if given a name
that is capitalized.

Anyways, maybe I got off to a bad start, but I'm a bit leery of the
language. In my estimation it's trying to be 'too clever by half', and
this coming from a veteran bash/perl programmer. I mean, free form is
one thing, but too much of a good thing can be harmful to your
programming health.

Blaming programming errors on non-existent bugs in the interpreter is
not a way to endear yourself.
And perhaps Python truly is not your style.
Maybe PyChecker or PyLint will help, I don't know.
I do not use them, but others swear
