Implement the unique_names method. When passed two arrays of names, it will
return an array containing the names that appear in either or both arrays.
The returned array should have no duplicates.

For example, calling unique_names(['Ava', 'Emma', 'Olivia'], ['Olivia', 'Sophia', 'Emma'])
should return an array containing Ava, Emma, Olivia, and Sophia in any order.


    def unique_names(names1, names2):
        return None

    names1 = ["Ava", "Emma", "Olivia"]
    names2 = ["Olivia", "Sophia", "Emma"]
    print(unique_names(names1, names2)) # should print Ava, Emma, Olivia, Sophia

from itertools import chain


def unique_names(names1, names2):
    return list(set(chain(names1, names2)))


names1 = ["Ava", "Emma", "Olivia"]
names2 = ["Olivia", "Sophia", "Emma"]
print(unique_names(names1, names2))     # should print Ava, Emma, Olivia, Sophia
