This function takes three arguments: 1 the type (here: new.instancemethod) 2 a function that takes an instance of the type. This returns a factory function and a tuple of the arguments this factory function needs to recreate the instance. 3 the factory function. In short the following must work, and out_method should do the same thing as in_method: factory, args = pickle_instancemethod(in_method) out_method = factory(*args) Now to your other problem, pickling static methods. The type of a static method is just new.function, the same as that of a global function. Global functions are already picklable, so the copy_reg mechanism doesn't kick in.
