class ordered_hash_set.OrderedSet(*items)

add(item)

Adds the item to set if it is not exist. Returns the index of added item (or already existing item) in the respective set. Raises TypeError if specified item is not hashable

Parameters:item – (object), item to be added.

clear()

Clears the set, removing all values.

contains(item)

contains_all(*items)

Determines whether this set contains all of the items in the specified collection or not.

Parameters:items – (tuple), the specified items to be searched. Returns:(bool), True if all of the items in the specified collection exist in this set, False otherwise.

contains_any(*items)

Checks whether any of the items exists in this set or not.

Parameters:items – (tuple), items to be searched. Returns:(bool), True if any of the items in the specified collection exist in this set, False otherwise.

difference(*other)

Returns a new set with elements in the set that are not in the others.

Parameters:*other –

(list | set | OrderedSet), The sets to check difference.

Returns:(OrderedSet) The set of the different elements.

drain(reverse=False)

Returns a iterator that removes items from set and yields them.

Parameters:reverse – If reverse is True items are yielded from end to start. Returns:(Iterator), iterator that consumes items.

get_all()

Returns a list containing all items.

Returns:(list), Specified list that contains all items in the set.

intersection(*other)

Returns a new ordered set with elements common to the set and all others.

Parameters:*other –

(list | set | OrderedSet), The sets to check common.

Returns:(OrderedSet) the set with elements common to the OrderedSet object and all *other.

is_disjoint(other)

Returns True if the set has no elements in common with other. Sets(also OrderedSets) are disjoint if and only if their intersection is the empty set.

Parameters:other – (list | set | OrderedSet), Checked object. Returns:(bool) If the set has no elements in common with other return True.

is_empty()

Determines whether this set is empty or not.

Returns:(bool), True if this set is empty, False otherwise.

is_subset(other)

Tests whether every element in the set is in other.

Parameters:other – (list | set | OrderedSet), Checked object. Returns:(bool) If the set is a subset of other return True.

is_superset(other)

Tests whether every element in other is in the set.

Parameters:other – (list | set | OrderedSet), Checked object. Returns:(bool) If the set is the superset of other return True.

remove(item)

Removes given item from set. Returns the used index of the removed item in the respective set. Raises ValueError if item is not found.

Parameters:item – (object), Removed item

remove_all(*items)

Removes all given items. Raises KeyError if any of the items is not found in the set.

Parameters:items – (tuple), Items to be removed.

union(*other)

Returns a new set with elements from the set and all others.

Parameters:*other –

(list | set | OrderedSet), The sets for union.

Returns:(OrderedSet) The new set with elements from the OrderedSet object and all others.

update(*items)

Adds multiple items at once. Raises TypeError, if any of these items are not hashable,

Parameters:items – (object), items, which must have __hash__ method, to be inserted.
