lihaijing d15bbada73 Replace six.iteritems() with .items()
1. As mentioned in [1], we should avoid using six.iteritems to achieve
   iterators. We can use dict.items instead, as it will return iterators
   in PY3 as well. And dict.items/keys will more readable.

2. In py2, the performance about list should be negligible,
   see the link [2].
