Tuple: ordered, immutable
Set: unique elements, unordered
Dictionary: key-value pairs, mutable
Quick Answer
List: mutable, ordered, allows duplicates [1, 2, 3]. Tuple: immutable, ordered, allows duplicates (1, 2, 3) - faster than list, used for fixed data. Set: mutable, unordered, unique elements {1, 2, 3} - O(1) membership test. Dict: mutable, key-value pairs, keys must be hashable {key: value}. Choose based on: mutability, order needs, uniqueness, and lookup pattern.
