It's not meant as a replacement; views form the new implementation of the keys(), values(), and items() methods in Python 3. The have been made available in Python 2 as viewkeys() etc. As said, they have the advantage of providing set operations (e.g., intersection with the keys of another dictionary), and they are more efficient than keys() or iterkeys(), because they have less overhead.
