Subject: [Tutor] Filtering out unique list elements

Dear All,

I have built a list with multiple occurrences of a string after some text processing that goes something like this:

[cat, dog, cat, cat, cat, dog, dog, tree, tree, tree, bird, bird, woods, woods]

I am wondering how to truncate this list so that I only print out the unique elements, i.e. the same list but with one occurrence per element:

[cat, dog, tree, bird, woods]

Any help much appreciated!

Regards,
Spyros
