set_theory, a Python code which demonstrates how set theory operations including union, intersection, complement, and symmetric difference.

We assume that a set is represented by a strictly ascending sequence of positive integers. We might think of a universal set U = 1 : N in cases where all our subsets will have elements between 1 and N.
