arr = random.sample(range(1, 1000000), 1000)

There is an array arr. How to split it into files no more than 3kb?

Answer 1

def chunkify(items, chunk_size):
    for i in range(0, len(items), chunk_size):
        yield items[i:i+chunk_size]


chunks = chunkify(arr, 128)

Each chunks element will be no larger than 3kb.
