Final answer:
The items() method is used to return all of a dictionary's keys and their associated values as a sequence of tuples.
Step-by-step explanation:
The method that returns all of a dictionary's keys and their associated values as a sequence of tuples is called items(). When this method is called on a dictionary, it generates a view of its items, which is a dynamic view that updates itself as the dictionary changes. The resulting view can be used in a for loop or converted into a list of tuples using the list() constructor.
For example, if we have a dictionary {'a': 1, 'b': 2}, calling .items() on this dictionary would result in [('a', 1), ('b', 2)].
