dict' object has no attribute 'iteritems' python 3 code example

Example: AttributeError: 'dict' object has no attribute 'iteritems'

As you are in python3 , use dict.items() instead of dict.iteritems()
iteritems() was removed in python3, so you can't use this method 
anymore. Take a look at Python 3.0 Wiki Built-in Changes section, 
where it is stated:

Removed dict.iteritems(), dict.iterkeys(), and dict.itervalues().

Instead: use dict.items(), dict.keys(), dict.values() respectively.
