print("Original List: ",L)
u_value = set( val for dic in L for val in dic.values())

# Basic syntax:
len(set(my_list))
# By definition, sets only contain unique elements, so when the list
# is converted to a set all duplicates are removed.
# Example usage:
my_list = ['so', 'so', 'so', 'many', 'duplicated', 'words']
len(set(my_list))
--> 4
# Note, list(set(my_list)) is a useful way to return a list containing
# only the unique elements in my_listpython list with only unique values
