Most objects have an attribute called '__dict__' that acts as a
container for the attributes of an object.

>>> class Container(object):
...     pass
...
>>> container = Container()
>>> d = {"hello": "world"}
>>> container.__dict__.update(d)
>>> container.hello
'world'

You can also implemenet __getattr__() like:

    def __getattr__(self, name):
        try:
            return self.data[name]
        except KeyError:
            raise AttributeError(name)
