The job is simple. We need to take a list, with duplicate elements in it and generate another list which only contains the element without the duplicates in them.
Input : [2, 4, 10, 20, 5, 2, 20, 4] Output : [2, 4, 10, 20, 5] Input : [28, 42, 28, 16, 90, 42, 42, 28] Output : [28, 42, 16, 90]
We can use not in on list to find out the duplicate items. We create a result list and insert only those that are not already not in.
[2, 4, 10, 20, 5]
