--- title: unique_elements tags: list --- Returns the unique elements in a given list. The given `list` is first converted to a `set` using the `set()` function. By definition, a `set` cannot have duplicate elements. So, the duplicate elements are automatically removed. Before returning, we convert it back to a `list` ```py def unique_elements(li): return list(set(li)) ``` ```py unique_elements([1, 2, 2, 3, 4, 3]) # [1, 2, 3, 4] ```
