Python set symmetric_difference_update(): Update with Exclusive Elements

A.symmetric_difference_update(other) changes A so it keeps elements present in exactly one of the two collections. It returns None and modifies the original set.

Use symmetric_difference() or ^ when you need a new set instead of changing the original mutable set.

Set order: sets are unordered. Whenever an example prints a set, the displayed element order can differ between runs or Python environments.
