A list is an ordered collection of elements so, we can add, remove, modify, and slicing elements in a list by using its position/index order. It allows duplicate elements.Setsare a collection of unique elements, similar to a list or atuple, but with some key differences. Sets do not a...
A Python set is an unordered collection of unique elements. It is useful because it can perform mathematical set operations such as union, intersection, and difference. Additionally, sets are faster to search than lists or dictionaries because they are implemented using hash tables, which have a ...
