Unlike lists or tuples, sets do not have a specific order, and they do not allow duplicate elements. Here are some key points about sets in Python: Uniqueness: Sets can only contain unique elements. If you try to add a duplicate element to a set, it will simply ignore it. No Order: Sets do not maintain the order of elements. When you add items to a set or iterate over it, you cannot rely on any specific order. Mutable: Sets are mutable, meaning you can add or remove items after creating them. Mathematical Operations: Sets support various mathematical operations like union, intersection, difference, and symmetric difference, which can be very useful in solving certain types of problems. Hashable Elements: Elements in a set must be hashable. This means that they must be immutable (like numbers, strings, or tuples containing only immutable elements). Mutable objects like lists cannot be added to a set because their contents can change, which would affect their hash value. Here's how you can create a set in Python: python Copy code my_set = {1, 2, 3} Or you can use the set() function: python Copy code my_set = set([1, 2, 3]) To add elements to a set, you can use the add() method: python Copy code my_set.add(4) To remove elements, you can use the remove() method: python Copy code my_set.remove(2) And you can perform various operations on sets like union, intersection, etc. For example: python Copy code set1 = {1, 2, 3} set2 = {3, 4, 5} union_set = set1.union(set2) # {1, 2, 3, 4, 5} intersection_set = set1.intersection(set2) # {3} Sets are commonly used when you need to work with unique elements or perform mathematical operations on collections of data.
