shuffle the possibly endless iterator by blocks Good shuffling over multiple files: block_shuffle(read_lines(files, shuffled_files=rand), rand=rand, block_size=100000) :param iter: the iterator we will yield shuffled items from :param block_size: size of memory to use for block shuffling :param rand: rand.shuffle will be used on the list block :return:
