Hi, Pythoners.

[AON LAZIO]

I have come across this code and I tried to figure out what does it do
First, I do not understand the sign @... above the class method, what does
it do?
Second, about the object in AnyWrapper(object), why do they declare "object"
as the superclass?
sometimes I saw (type) what the differences between "object" and "type"?


from ib.lib.overloading import overloaded

class AnyWrapper(object):
    @overloaded
    def error(self, e):
        raise NotImplementedError()
    @error.register(object, str)
    def error_0(self, strval):
        raise NotImplementedError()

Thanks in advance
