'In Python3, Why list object is an iterable but not iterator directly?
I do know object implemented iter() is a iterable, and next is a iterator. but i'm confused why list object in python3 doesn't implement next directly.
l = list((1,2,3))
l_iterator = l.__iter__()
l_iterator.__next__()
...
is there some ingenious mechanism i missed?

You only need to use the double underscores when defining iterator and next methods for a custom class. I think in this case, here is what you are looking to do:
l = list((1,2,3))
l_iterator = iter(l)
next(l_iterator)
