Problem: Hello guys, I found python list is fun. I was doing some operation with a python list. Let me say, I have a python list looks: is_a_list = [1, 5, 3, 6, 3, 5, 6, 1] with mixed of duplicate values in it. Now, I am willing to remove all the duplicate elements from the list. How do you do that in an easiest and efficient way? I am eagerly waiting for your answers. Thanks.
