我需要一次仅处理10类型的字典所以我需要划分这个字典成部分，使得每个子部分可以有最多10个元素（键/值对）。

API调用我需要使这种格式最多可以取10个值，所以我需要按部分来处理零件。

例子：

for data in data_in_chunks_of_10: 
    api_call(data)

如何做到这一点有效？

你尝试过什么那效率不够高？ –

关于如何在结果字典中分配密钥的任何要求？ – MSeifert

这个问题对我来说很不清楚。 –

你可以使用一个发电机返回数据块在你需要的块大小如下：

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

这会给你两个数据块如下：

[(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'})]
