Symmetric Difference

Elements in exactly one set

Symmetric difference finds elements in either set but not both:

a = {1, 2, 3}
b = {2, 3, 4}

exclusive = a ^ b                       # {1, 4}
exclusive = a.symmetric_difference(b)   # Same result

This is like union minus intersection. Elements that appear in exactly one set, not both.

Symmetric difference is order-independent: a ^ b equals b ^ a.
