Great solution, unfortunately the return value is not a tuple as in the OP version. Maybe in this way? def powers_of_2_inB(n): bc = (n ^ (n - 1)).bit_count() - 1 return bc, int(n / (1 << bc)) Good point. I overlooked that. I should have written: def powers_of_2_in(n): bc = (n ^ (n - 1)).bit_count() - 1 return bc, n >> bc -- https://mail.python.org/mailman/listinfo/python-list
