You can use a set to do the job. Remember that members in the set are unique,
duplicate members are ignored.
Before you start the for loop, create a set:
names = set()
Instead of `print name`, you add the name to the set:
names.add(name)
Note that if name already exists, because members of a set are unique,
the name is (at least conceptually) ignored.
Once the for loop is completed, you print the remaining names.
print names (Python 2)
or
print(names) (Python 3)
