Unique Elements in Python Lists

Introduction

In Python, a list is a collection of items that are ordered and changeable. Sometimes, we need to find the unique elements in a list, which means we want to remove any duplicates and only keep the distinct values. In this challenge, you will write a function that takes a list as input and returns a new list containing only the unique elements.

Unique Elements in List

Write a Python function called unique_elements that takes a list as input and returns a new list containing only the unique elements. Your function should perform the following steps:

Create a set from the list to discard duplicated values.
Return a list from the set.

Your function should have the following signature:

def unique_elements(li: List) -> List:

def unique_elements(li):
  return list(set(li))

unique_elements([1, 2, 2, 3, 4, 3]) ## [1, 2, 3, 4]

Summary

In this challenge, you have written a Python function that takes a list as input and returns a new list containing only the unique elements. You have learned how to use sets to remove duplicates and how to convert a set back to a list.
