try this one:

        def ls(s, c='/'):
            parts = s.split(c)
            d = {}
            for p in parts:
                if not d.has_key(len(p)):
                    d[len(p)] = []
                d[len(p)].append(p)
            k = d.keys()
            k.sort()
            return d[k[-1]]

        print ls('abcd/df/a/iiwk/abcdefghijkl/b/c')

it returns a list with the longest strings
