In case it still isn't quite clear, a decorator is just syntactic sugar around wrapping something with something else, aliasing the original function, if you will. But there's no reason it has to be JUST for functions...
>>> def wrapper(cls):
... class Eggs:
... def __init__(self, other):
... print("pretending to be {0}".format(other))
... self.other = other()
... def inner():
... return Eggs(cls)
... return inner
...
>>> @wrapper
... class Spam:
... def __init__(self):
... print("SPAM!")
...
>>> x = Spam()
pretending to be <class '__main__.Spam'>
SPAM!I can't actually think of a use for that which wouldn't be better served by just using inheritance, but if such a situation arises, it is possible.
