To fix this you could: Also to save two operations you could get the the symmetric difference of two, union with the third, then do the difference of the union of the intersections of the first and third and second and third. This operator is used to return the symmetric difference of two sets just like symmetric_difference () method. In set theory, the symmetric difference between two sets (A and B) is also referred to as the disjunctive join.
