That's incredibly clever! I would had never thought to use "zip" to do this ! I would had only think to use it for the contrary, i.e. >>> zip([1,2,3], [4,5,6]) [(1, 4), (2, 5), (3, 6)] Notice though that the solution doesn't yield the exact contrary as we end up with a list of tuples instead of a list of lists : >>> zip(*[(1,4),(2,5),(3,6)]) [(1, 2, 3), (4, 5, 6)] But this can be easily fix if lists are really wanted : >>> map(list, zip(*[(1,4),(2,5),(3,6)])) [[1, 2, 3], [4, 5, 6]] Anyway, I find Diez solution brillant ! I'm always amazed to see how skilled a programmer can get when comes the time to find a short and sweet solution. One can admire that zip(*zip(*a_list_of_tuples)) == a_list_of_tuples Thank you You gave me much to enjoy Francis girard -- http://mail.python.org/mailman/listinfo/python-list
