Keep the flattened data array others suggested, and then just split it like this: *(replace `example_data`, `_array`, and `columns`)* >>> example_data = range(15) >>> split_array = lambda _array, colums: \ . . . [_array[i:i + colums] for i in \ . . . xrange(0, len(_array), colums)] >>> print split_array(example_data, 5) [[0, 1, 2, 3, 4], [5, 6, 7, 8, 9], [10, 11, 12, 13, 14]] Gist <https://gist.github.com/anonymous/f9064e4c8790ae037ec6> What do you guys think?
