This class definition looks muddled. Because Test2 inherits from dict,
the object referred to by "self" will be a dict, and self.__dict__ is
actually a *different* dict, containing the attributes of self. The
line:

    self.__dict__ = {'key', 'value'}

is essentially equivalent to:

    self.key = value

and will be regardless of whether you inherit from object or dict. If
you find this distinction confusing, then I recommend not inheriting
from dict.
