You give lot of comments and I agree with most of them.

I suggest to avoid such usage of or/and (expecially for newbies), that
is triky and can produce bugs, and to use a more explicit if:

    def __init__(self, answers=None):
        if answers is None:
            self.answers = {}
        else:
            self.answers = answers

If you are sure you can use 2.5+ (the enclosing of the if is optional,
but helps readability):

    def __init__(self, answers=None):
        self.answers = ({} if answers is None else answers)
