The :class:`set` type is mutable --- the contents can be changed using methods like :meth:`add` and :meth:`remove`. Since it is mutable, it has no hash value and cannot be used as either a dictionary key or as an element of another set. -The :class:`frozenset` type is immutable and :term:`hashable` --- its contents cannot be -altered after it is created; it can therefore be used as a dictionary key or as -an element of another set. +The :class:`frozenset` type is immutable and :term:`hashable` --- its contents +cannot be altered after it is created; it can therefore be used as a dictionary +key or as an element of another set. -Non-empty sets (not frozensets) can be created by placing a comma-separated list -of elements within braces, for example: ``{'jack', 'sjoerd'}``, in addition to the -:class:`set` constructor. +As of Python 2.7, non-empty sets (not frozensets) can be created by placing a +comma-separated list of elements within braces, for example: ``{'jack', +'sjoerd'}``, in addition to the :class:`set` constructor.
