all Python 3Sets (set)function

frozenset.symmetric_difference

frozenset

Return a new frozenset — the symmetric difference of the two sets.

Syntax

f.symmetric_difference(other)

The symmetric difference keeps items that occur in exactly one of the sets — the union minus the intersection. Unlike union() or difference(), this method takes exactly one argument, so three sets cannot be folded in a single call. The ^ operator computes the same result but requires sets on both sides.

Examples

print(frozenset({1, 2}).symmetric_difference({2, 3}))   # → frozenset({1, 3})
print(frozenset({1, 2}).symmetric_difference({3, 4}))   # → frozenset({1, 2, 3, 4})
print(frozenset({1, 2, 3}).symmetric_difference([3, 4]))   # → frozenset({1, 2, 4})
print(sorted(frozenset('abc').symmetric_difference('bcd')))   # → ['a', 'd']
print(frozenset({1, 2}).symmetric_difference({1, 2}))   # → frozenset()
print(frozenset({1, 2}) ^ {2, 3})   # → frozenset({1, 3})
