Python union list of sets | Example code

Union of the list using sets will Lists without repetition of common elements in Python. The Union of two lists means it will contain all the elements of both lists.

Example union list of sets in Python

Simple example code union of two lists using set.

l1 = [1, 2, 3, 4, 5]
l2 = [2, 4, 6, 8, 10]

res = list(set(l1 + l2))

print(res)

Output:

OR

Using the Union method.

l1 = [1, 2, 3, 4, 5]
l2 = [2, 4, 6, 8, 10]

res = list(set(l1).union(set(l2)))

print(res)

Note: the order of elements in the resulting set may not be the same as the original order of elements in the sets list, as sets are unordered collections in Python.
