fromkeys(original_items)) That will de-duplicate your items while keeping them in the order that each item was first seen.If you'd like practice de-duplicating list items, try out the uniques_only Python Morsels exercise. The bonuses include some twists that weren't discussed above. 😉...

It's useful to clarify what we mean byduplicate valuesbefore presenting solutions to remove them from a list. Two objects are generally considered to be duplicates when their values are equal. In Python, the equality operator==returnsTruewhen two objects have the same value. Objects of different...
