python - Can I create a class which can be unpacked? -

-
for example: x = (1, 2) a,b = x now i'd accomplish in case of x being instance of class isn't list or tuple. overriding __getitem__ or __getslice__ doesn't work: class test(object): def __getitem__(self, key): return 1 a,b = test() results in valueerror: many values unpack . can make work without inheriting list or tuple (or respective userx classes)? or under-the-hood magic cannot use? you need override __iter__ or __getitem__ . here's example using __iter__ : class test(object): def __iter__(self): return iter([1, 2]) a,b = test() be careful, __iter__ needs return iterator. easiest way either wrap data structure in iter , or have yield generator. for example of using __getitem__ , see jonrsharpe's excellent answer.
