Python Sets — Union, Intersection, Difference + O(1) Lookup | Ep 14 of 20

Sets give you O(1) membership testing and elegant mathematical operations. This episode makes union, intersection, difference, and symmetric difference completely intuitive — with the performance comparison that will make you rethink how you check membership.
What you'll learn: • Set creation and automatic deduplication • Union |, Intersection &, Difference -, Symmetric ^ • add() vs discard() vs remove() • Why sets beat lists for membership testing
