Ordered Set Recipe¶
- class sortedcollections.OrderedSet(iterable=())[source]¶
Like OrderedDict, OrderedSet maintains the insertion order of elements.
For example:
>>> ordered_set = OrderedSet('abcde') >>> list(ordered_set) == list('abcde') True >>> ordered_set = OrderedSet('edcba') >>> list(ordered_set) == list('edcba') True
OrderedSet also implements the collections.Sequence interface.
- __str__()¶
Text representation of set.
- __weakref__¶
list of weak references to the object
- count(key)¶
key in ordered_set
