📘 NAME

builtins.frozenset = class frozenset(object)

frozenset() -> empty frozenset object
frozenset(iterable) -> frozenset object

Build an immutable unordered collection of unique elements.

🚀 Quick Reference

Use Case	Command	Description
🧪 Create empty frozenset	frozenset()	Creates an empty immutable set
📦 Create frozenset from iterable	frozenset([1,2,3])	Creates immutable set from list
🔍 Check membership	x in fs	Test if element is in frozenset
📏 Get size	len(fs)	Number of elements
🔗 Union	fs1 | fs2	All elements in either set
🔗 Intersection	fs1 & fs2	Elements in both sets
🔗 Difference	fs1 - fs2	Elements in fs1 but not fs2
🔗 Symmetric difference	fs1 ^ fs2	Elements in exactly one set
🔗 Subset check	fs1 <= fs2	Is fs1 subset of fs2?
🔗 Superset check	fs1 >= fs2	Is fs1 superset of fs2?
🔗 Disjoint check	fs1.isdisjoint(fs2)	Do sets have no common elements?
