Ezio Melotti <ezio.melo...@gmail.com> added the comment: Should we add permutations with repetitions?
Example (from Schaum's outline of theory and problems of probability and statistics): The number of different permutations of the 11 letters of the word MISSISSIPPI, which consists of 1 M, 4 I's, 4 S's and 2 P's, is 11! / (1!*4!*4!*2!) = 34650 math.perms_with_repetitions(11, [1,4,4,2]) and maybe parallel function in itertools: itertools.permutations_with_repetitions(iterable[, r]) This should be equal to itertools.permutations(set(iterable)[, r]). _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5139> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
