Getting a distinct set of values from objects in a list in python

Question

Let's say that I have the following list consisting of a set of objects:

people = [("John","Smith"), ("Jane","Doe"), ("Jane","Smith")]

The objects are created via a separate class which has person.getFirstName and person.getLastName defs.

How can I parse the list such that I end up with a separate list of values consisting of

 uniqueNames = ["Smith","Doe"]

using list comprehension might do what you need:

>>> people = [("John","Smith"), ("Jane","Doe"), ("Jane","Smith")]
>>> uniqueNames = list(set(i[1] for i in people))
>>> uniqueNames
['Smith', 'Doe']
