just have a look at this tutorial: and look for Lists and Sets
http://docs.python.org/tut/tut.html

and look in the reference index for set() and list() in
http://docs.python.org/lib/genindex.html


or just pick the algo in another language in the url you give

or tell us precisely what part of the python algo you do not understant!
