SET in Python | Operations on SET Part 2 | Basic Operations on SET

Hi Learners,
In Python, a set is an unordered collection of unique elements. Here are some common operations for sets in Python:

Creating a set: A set can be created using curly braces {} or by using the set() constructor. For example, s = {1, 2, 3} creates a set s with the values 1, 2, and 3.

Adding elements to a set: Elements can be added to a set using the add() method. For example, s.add(4) adds the element 4 to the set s.

Removing elements from a set: Elements can be removed from a set using the remove() or discard() method. For example, s.remove(2) removes the element 2 from the set s.

Union of sets: The union of two or more sets can be obtained using the union() or | operator. For example, s1 = {1, 2, 3} and s2 = {3, 4, 5} can be combined to create a new set s3 as s3 = s1.union(s2) or s3 = s1 | s2.

Intersection of sets: The intersection of two or more sets can be obtained using the intersection() or & operator. For example, s1 = {1, 2, 3} and s2 = {3, 4, 5} can be intersected to create a new set s3 as s3 = s1.intersection(s2) or s3 = s1 & s2.

Difference of sets: The difference between two sets can be obtained using the difference() or - operator. For example, s1 = {1, 2, 3} and s2 = {3, 4, 5} can be subtracted to create a new set s3 as s3 = s1.difference(s2) or s3 = s1 - s2.

Symmetric difference of sets: The symmetric difference between two sets can be obtained using the symmetric_difference() or ^ operator. For example, s1 = {1, 2, 3} and s2 = {3, 4, 5} can be combined to create a new set s3 as s3 = s1.symmetric_difference(s2) or s3 = s1 ^ s2.

Checking membership: You can check if an element is present in a set using the in operator. For example, 2 in s returns True if the value 2 is present in the set s.

Finding the length: The length of a set can be found using the len() function. For example, len(s) returns the number of elements in the set s.

These are some of the common operations that can be performed on sets in Python. It is important to note that sets are unordered, and therefore, indexing is not supported for sets.
