Are Python Sets Ordered
No, Python sets are unordered collections of unique elements. This means that the items in a set have no index or order, and that each item in the set must be unique.
Sets are useful for tasks such as removing duplicates from a list, testing for membership in a collection, and performing mathematical set operations (such as union, intersection, and difference).
If you need an ordered collection in Python, you can use a list or a tuple instead. Lists and tuples maintain the order of their elements and can be indexed and sliced just like arrays in other programming languages.
