The most efficient way to obtain unique values from a list is to convert it to a set.
my_list = ['Dog', 'Cat', 'Bird', 'Dog']my_set = set(my_list)print(my_set)
{'Dog', 'Bird', 'Cat'}
NOTE
By definition, a set only contains unique values and does not allow for duplicates.
If you need to use the result as a list again we can simply convert the set back to a list:
new_list = list(my_set)print(new_list)
['Dog', 'Bird', 'Cat']
