Question

我的数据格式如下：

{0: {'offer_id': u'308249', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 1: {'offer_id': u'308255', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 2: {'offer_id': u'283063', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 3: {'offer_id': u'313467', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 4: {'offer_id': u'313673', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 5: {'offer_id': u'324519', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 6: {'offer_id': u'320501', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 7: {'offer_id': u'320503', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 8: {'offer_id': u'323593', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 9: {'offer_id': u'323595', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 10: {'offer_id': u'324441', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 11: {'offer_id': u'324443', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 12: {'offer_id': u'325129', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 13: {'offer_id': u'325131', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 14: {'offer_id': u'325133', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 15: {'offer_id': u'325135', 'affiliate_id': u'1014', 'approval_status': 'approved'}}

我需要一次只处理10个dicts 我需要将这个dict分成几部分，这样每个子部分最多可以有10个元素（键/值对）。

我需要进行的API调用最多可以采用这种格式的10个值，因此我需要逐个处理零件。

示例：

for data in data_in_chunks_of_10:
    api_call(data)

我如何有效地实现这一目标？

您可以使用生成器按照所需的块大小返回数据块：

def blocks(data, n=10):
    for i in xrange(0, len(data), n):
        yield data[i:i+n]

data = {
    0: {'offer_id': u'308249', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    1: {'offer_id': u'308255', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    2: {'offer_id': u'283063', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    3: {'offer_id': u'313467', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    4: {'offer_id': u'313673', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    5: {'offer_id': u'324519', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    6: {'offer_id': u'320501', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    7: {'offer_id': u'320503', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    8: {'offer_id': u'323593', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    9: {'offer_id': u'323595', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    10: {'offer_id': u'324441', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    11: {'offer_id': u'324443', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    12: {'offer_id': u'325129', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    13: {'offer_id': u'325131', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    14: {'offer_id': u'325133', 'affiliate_id': u'1014', 'approval_status': 'approved'}, 
    15: {'offer_id': u'325135', 'affiliate_id': u'1014', 'approval_status': 'approved'}}

for block in blocks(data.items(), 10):
    print block

这将为您提供两个数据块，如下所示：

[(0, {'offer_id': u'308249', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (1, {'offer_id': u'308255', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (2, {'offer_id': u'283063', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (3, {'offer_id': u'313467', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (4, {'offer_id': u'313673', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (5, {'offer_id': u'324519', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (6, {'offer_id': u'320501', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (7, {'offer_id': u'320503', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (8, {'offer_id': u'323593', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (9, {'offer_id': u'323595', 'affiliate_id': u'1014', 'approval_status': 'approved'})]
[(10, {'offer_id': u'324441', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (11, {'offer_id': u'324443', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (12, {'offer_id': u'325129', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (13, {'offer_id': u'325131', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (14, {'offer_id': u'325133', 'affiliate_id': u'1014', 'approval_status': 'approved'}), (15, {'offer_id': u'325135', 'affiliate_id': u'1014', 'approval_status': 'approved'})]

将dicts的字典划分为特定部分
