How do you make a list of unique numbers in Python?

Use a set to get the unique numbers. Then, turn the set into a list. It’s helpful to think “inside out” when reading the above code. The innermost code gets evaluated first: set (numbers). Then, the outermost code is evaluated: list (set (numbers)). Iteration is another approach to consider.
