In this assignment you will extend the 'dictionary' class by adding a new subclass and four methods. The new class should be called 'NewDict' and must be a subclass of 'dict'. The new methods will provide functions that are not directly included in the basic dictionary class.They are: displaysorted0 - displays the contents of the dictionary in ascending key order addfromlist() - adds the contents of a list to the dictionary using the first list element as the key and the rest as the value retrieve) - returns the list of values using the keys provided in a list of keys merge) - merges in the contents of an input dictionary resulting in a new dictionary containing the original plus the input Specification requirements for each method are in the table below Method Name displaysorted Depending on the value of an input Purpose Input Output/returns display D-display list R' Return st R B'- do both Default - 'D return list B- display and return list parameter, displays the contents of the dictionary in ascending key-sorted order, returns a list consisting of the key and values in sorted order, or does both.
