use a python 2&3 compatible method to get the "first" value of dict:

a={'aaa':111, 'bbb':222}

print (a[list(a)[0]])

    py33: 'dict_keys' object does not support indexing

    In python 3, dict.keys() is a class of 'dict_keys', it does not
    support indexing.

    Cast the dict to list to get the "first" value of dict, which is
    compatible with python 2&3.

    Closes-Bug: #1229005
