How to do it...

With a little effort, we can create a class that leverages dictionaries to contain any attribute we want and allow access both as a dictionary and through properties:

>>> class Bunch(dict):
...    def __getattribute__(self, key):
...        try: 
...            return self[key]
...        except KeyError:
...            raise AttributeError(key)
...    
...    def __setattr__(self, key, value): 
...        self[key] = value
...
>>> b = Bunch(a=5)
>>> b.a
5
>>> b['a']
5
