Set vs List

Key Differences Between list and set

Order:

List: Ordered collection of elements. The order in which elements are specified is preserved. Set: Unordered collection of unique elements. The order is not preserved and elements must be unique.

Uniqueness:

List: Can contain duplicate elements. Set: Cannot contain duplicate elements; all elements must be unique.

Indexing:

List: Supports indexing to access elements by their position (e.g., list[0]). Set: Does not support indexing because there is no guaranteed order.
