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"?

Object is the base class. Type is the base metaclass. Reread the class
statement doc. @statements are decorators. I believe they are
documented along with function statements, though in 3.0 they apply to
classes also.

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
