you use them all the time: plain old instance objects...
here's a rather horrid piece of code that turns a list of dictionaries
into a single object the automatically searches the dictionary chain
when you ask for attributes (use getattr for non-standard keys).
def flatten_dicts(*dicts):
root = None
for dict in dicts:
class wrapper: pass
if root:
wrapper.__bases__ = (root,)
wrapper.__dict__ = dict
root = wrapper
return wrapper()
obj = flatten_dicts(d1, d2, d3)
