Hello everybody, welcome back to Programming In Python. Here in this post am going to tell you how to find the union of two lists in Python. Generally, Union means getting all the unique elements in both lists. So here I will take two lists and convert them to a set and then apply the union function on it to find all the unique elements n both lists. Not only for two lists the same way we can find the union of any number of lists.
__author__ = 'Avinash'
lst = []
num = int(input("Enter size of list 1: \t"))
for n in range(num):
numbers = int(input("Enter any number: \t"))
lst.append(numbers)
lst2 = []
num2 = int(input("Enter size of list 2: \t"))
for n in range(num2):
numbers2 = int(input("Enter any number: \t"))
lst2.append(numbers2)
union = list(set().union(lst, lst2))
print("\nThe Union of two lists is \t", union)
