How do I combine lists so that each element of each list appears only once?

Sonja , thera are many ways to accomplish this task. 2 of them are: lst1 = [1, 2, 3, 4] lst2 = [4, 5, 2, 7] result should be: [1, 2, 3, 4, 5, 7] (1) we can use the plus operator to merge lst1 and lst2. then make the resulting list a set, and convert it back to a list. (2) we can use a for loop. append elements from lst2 to lst1 only if these elements don't exist already in in lst1
