PythonBeginner

Python

# Program to find union of two lists

list1 = input("Enter first list elements: ").split()
list2 = input("Enter second list elements: ").split()

union = list(set(list1) | set(list2))

print("Union:", union)

Output

Enter first list elements: 1 2 3
Enter second list elements: 3 4 5
Union: ['1', '2', '3', '4', '5']

We use set union (|) to collect all distinct elements from both lists.
