Just mentioning it here again, but "type(a).__index__(a)" is still not perfectly correct. Attached is a case where it differs. I think you get always the correct answer by evaluating "range(a).stop". It's admittedly obscure... For example: class A: def __index__(self): return -42**100 a = A() print(range(a).stop)
