The following relies on undocumented (I hope) behaviour: >>> preferences = [10, 30, 20] >>> hosts = [ "mx1.domain.com", "anotherhost.domain.com", "mx2.domain.com"] >>> hosts.sort(key=lambda x, p=iter(preferences).next: p()) >>> preferences.sort() >>> hosts ['mx1.domain.com', 'mx2.domain.com', 'anotherhost.domain.com'] >>> preferences [10, 20, 30] Don't do it, use a list of tuples as already suggested.
