2.4 doc:
reversed( seq)
Return a reverse iterator. seq must be an object which supports the
sequence protocol (the __len__() method and the __getitem__() method
with integer arguments starting at 0). New in version 2.4.
[no mention of __reversed__]
3.3.6 Additional methods for emulation of sequence types
[ditto]
However, I confirmed that __reversed__ is used by reverse()
class C:
def __reversed__(self): return 'abc'
c=C()
print(reversed(c))
>>>
abc
