In Python, there are numerous techniques to merge two or more sets.

You can use the union() function to create a new set that has all of the items from both sets, or you can use the update() method to insert all of the things from one set into another.

Code:

x = {"a", "b" , "c"}

y = {1, 2, 3}

z = x.union(y)

print(z)

Output:

{2, ‘b’, 1, ‘c’, ‘a’, 3}

Keep Only the Duplicates

The elements present in both sets will be kept by the intersection update() function.

Code:

x = {1,2,3}

y = {3,4,5}

x.intersection_update(y)

print(x)

Output:

3
