This leads on to performing set operations such as union, intersection difference, and other set operations. Dictionaries are mutable, so you can add and. You will then create and initialize sets.
The returned list is a view of the items of the dictionary, meaning that any changes done to the dictionary will be reflected in the items list. A dictionary or dict is an object that maps a set of named indexes called keys to a set of corresponding values. We can iterate through dictionary keys one by one using a for loop. Meaning a dictionary maintains the order of its items.

The items () method will return each item in a dictionary, as tuples in a list. A dictionary is an ordered collection of items (starting from Python 3.7).
