Create a Python function to accept a list and return a list consisting of unique positive elements only.
Create a Python function that takes a list of integers (which could be positive or negative) and returns a new list with only the unique positive integers present in the original list. ### Parameters - `lst` (list): A list of integers that can contain both negative and positive values. ### Returns - A list of unique positive integers derived from the input list. ### Examples ```python distinct_positive_integers([-5, 1, -7, -5, -2, 3, 3, -5, -1, -1]) # Returns: [1,3] distinct_positive_integers([3, -3, -3, 5, 5, -6, -2, -4, -1, 3]) # Returns: [3, 5] distinct_positive_integers([10, 6, -12, 13, 5, 5, 13, 6, 5]) # Returns: [10, 6, 13, 5] ```
