Data Structures – Sets

Data Structures – Sets\n\nSets store unique, unordered items and support mathematical operations like union, intersection, and difference.\n\npython\nprimes = {2, 3, 5, 7}\nprimes.add(11)\nprimes.update([13, 17])\nprint('All primes:', primes)\n\n# Set operations\neven = {2, 4, 6, 8}\nprint('Intersection:', primes & even) # {2}\nprint('Union:', primes | even) # all unique numbers\n\n\nBecause sets discard duplicates automatically, they’re great for membership testing (x in my_set).\n
