Sets being mutable are unhashable, so they can't be used as dictionary keys. On the other hand, frozensets are hashable and can be used as keys to a dictionary. Frozensets can be created using the frozenset() function.

Sets can also be used to perform mathematical set operations like union, intersection, symmetric difference, etc. Creating Python Sets. A set is created by placing all the items (elements) inside curly braces {}, separated by comma, or by using the built-in set() function.

The None is a singleton object of the NoneType class. It means that Python creates one and only one None object at runtime. Therefore, if you use the equality ( ==) or is operator to compare None with None, you’ll get the result of True: print ( None == None ) print ( None is None)
