Example: >>> data = range(10) >>> list(block_splitter(data, 3)) [[0, 1, 2], [3, 4, 5], [6, 7, 8], [9]] If the ``block_size`` is greater than the total length of ``data``, a single block will be generated: >>> data = range(3) >>> list(block_splitter(data, 4)) [[0, 1, 2]] :param data: Any iterable. If ``data`` is a generator, it will be exhausted, obviously. :param int block_site: Desired (maximum) block size.
