dhp.VI
======
These are simple methods for dealing with Python 2/3 compatibility issues.  They are focused on solving the problems of python 2/3 support in the dhp package.  If you need more see `six <https://pypi.python.org/pypi/six>`_

.. _iteritems-link:

iteritems
---------
return the proper iteritems method for a dictionary based on the version of Python

.. function:: iteritems(dct)

   return proper iteritems method

   :param dct: dictionary
   :rtype: iterable method

.. code:: python

    from dhp.VI import iteritems

    for k, val in iteritems(my_dict):
