[dharmendra]

In py3 dict.keys() returns a dict_keys object which behaves a lot more like a set than a list.

Please see the bellow error logs:

    Fix dict.keys() TypeError issue.

    In python3, dict.keys() returns a dict_keys object rather than
    a list. This patch will make it compatible with py3 as well as py2.
