Python: 列表分成子列表，數組分成子數組

1. 大列表分拆

# python 將一個大數組根據固定量分成幾個小數組
    codes_batch_num = 2
    pure_codes = ['0000001.SZ', '0000002.SZ', '0000003.SZ', '0000004.SZ', '0000005.SZ', '0000006.SZ', '0000007.SZ']
    code_arrays = [pure_codes[idx:idx + codes_batch_num] for idx in range(0, len(pure_codes), codes_batch_num)]
