Method Details

init(self, iterable=None)
(Constructor)

Construct a set from an optional iterable.

Overrides:: sets.BaseSet.__init__

hash(self)
(Hashing function)

A Set cannot be hashed.

Overrides:: __builtin__.object.__hash__

iand(self, other)

Update a set with the intersection of itself and another.

ior(self, other)

Update a set with the union of itself and another.

isub(self, other)

Remove all elements of another set from this set.

ixor(self, other)

Update a set with the symmetric difference of itself and another.

add(self, element)

Add an element to a set.

This has no effect if the element is already present.

clear(self)

Remove all elements from this set.

difference_update(self, other)

Remove all elements of another set from this set.

discard(self, element)

Remove an element from a set if it is a member.

If the element is not a member, do nothing.

intersection_update(self, other)

Update a set with the intersection of itself and another.

pop(self)

Remove and return an arbitrary set element.

remove(self, element)

Remove an element from a set; it must be a member.

If the element is not a member, raise a KeyError.

symmetric_difference_update(self, other)

Update a set with the symmetric difference of itself and another.

union_update(self, other)

Update a set with the union of itself and another.

update(self, iterable)

Add all values from an iterable (such as a list or file).
