Opposite of set.intersection in python? -


in python can use a.intersection(b) find items common both sets.

is there way disjoint opposite version of this? items not common both a , b; unique items in a unioned unique items in b?

you looking symmetric difference; elements appear in set or in set b, not both:

a.symmetric_difference(b)

from set.symmetric_difference() method documentation:

return new set elements in either set or other not both.

you can use ^ operator too, if both a , b sets:

a ^ b

while set.symmetric_difference() takes iterable other argument.

the output equivalent of (a | b) - (a & b), union of both sets minus intersection of both sets.
