このlist-dict jsonレスポンスからKey-Valueのみを抽出する方法は？

Question

私は、このJSONレスポンスからキーと値のみを抽出することができますどのように希望：

[{u'SkuSellersInformation': [{u'Name': u'site', u'Price': 409, u'IsDefaultSeller': True, u'AvailableQuantity': 2, u'LogoUrl': None, u'SellerId': u'1', u'ListPrice': 409}], u'BestInstallmentNumber': 10, u'RealWeightKg': 100.0, u'NotifyMe': True, u'HasServiceAtCartPage': False, u'RewardValue': 0.0, u'ListPrice': 409, u'Name': u'Light Blue Eau de Toilette Dolce & Gabbana - Perfume Feminino - 50ml', u'HasExtendedWarranty': False, u'BestInstallmentValue': 40.9, u'Ean': u'0737052074313', u'Price': 409, u'RealWidth': 10.0, u'IdProduct': 909, u'AvailabilityMessage': u'True', u'HasServiceAtServicePage': False, u'RealLength': 10.0, u'RealHeight': 10.0, u'HasServiceAtProductPage': False, u'SalesChannel': u'1', u'DefaultSellerId': u'1', u'Reference': u'002796', u'HasExtendedWarrantyPage': False, u'Id': 5293, u'Images': [[{u'Path': u'http://site.vteximg.com.br/arquivos/ids/183280-320-320/light-blue-edt-dg-2.jpg', u'ArchiveTypeId': 2, u'Name': None, u'IdArchive': u'183280', u'IsMain': False}, {u'Path': u'http://site.vteximg.com.br/arquivos/ids/183280-55-55/light-blue-edt-dg-2.jpg', u'ArchiveTypeId': 3, u'Name': None, u'IdArchive': u'183280', u'IsMain': False}, {u'Path': u'http://site.vteximg.com.br/arquivos/ids/183280-65-65/light-blue-edt-dg-2.jpg', u'ArchiveTypeId': 1, u'Name': None, u'IdArchive': u'183280', u'IsMain': False}, {u'Path': u'http://site.vteximg.com.br/arquivos/ids/183280-500-500/light-blue-edt-dg-2.jpg', u'ArchiveTypeId': 10, u'Name': None, u'IdArchive': u'183280', u'IsMain': False}, {u'Path': u'http://site.vteximg.com.br/arquivos/ids/183280-120-120/light-blue-edt-dg-2.jpg', u'ArchiveTypeId': 29, u'Name': None, u'IdArchive': u'183280', u'IsMain': False}, {u'Path': u'http://site.vteximg.com.br/arquivos/ids/183280-130-130/light-blue-edt-dg-2.jpg', u'ArchiveTypeId': 30, u'Name': None, u'IdArchive': u'183280', u'IsMain': False}], [{u'Path': u'http://site.vteximg.com.br/arquivos/ids/187857-320-320/light-blue-eau-de-toilette-dolce-gabbana-perfume-feminino.jpg', u'ArchiveTypeId': 2, u'Name': None, u'IdArchive': u'187857', u'IsMain': True}, {u'Path': u'http://site.vteximg.com.br/arquivos/ids/187857-55-55/light-blue-eau-de-toilette-dolce-gabbana-perfume-feminino.jpg', u'ArchiveTypeId': 3, u'Name': None, u'IdArchive': u'187857', u'IsMain': True}, {u'Path': u'http://site.vteximg.com.br/arquivos/ids/187857-65-65/light-blue-eau-de-toilette-dolce-gabbana-perfume-feminino.jpg', u'ArchiveTypeId': 1, u'Name': None, u'IdArchive': u'187857', u'IsMain': True}, {u'Path': u'http://site.vteximg.com.br/arquivos/ids/187857-500-500/light-blue-eau-de-toilette-dolce-gabbana-perfume-feminino.jpg', u'ArchiveTypeId': 10, u'Name': None, u'IdArchive': u'187857', u'IsMain': True}, {u'Path': u'http://site.vteximg.com.br/arquivos/ids/187857-120-120/light-blue-eau-de-toilette-dolce-gabbana-perfume-feminino.jpg', u'ArchiveTypeId': 29, u'Name': None, u'IdArchive': u'187857', u'IsMain': True}, {u'Path': u'http://site.vteximg.com.br/arquivos/ids/187857-130-130/light-blue-eau-de-toilette-dolce-gabbana-perfume-feminino.jpg', u'ArchiveTypeId': 30, u'Name': None, u'IdArchive': u'187857', u'IsMain': True}]], u'Availability': True}] 

私はこの方法を試してみましたが、それでもこれはサブリスト内のいくつかのdicts

import urllib2 
import json 

response = urllib2.urlopen('http://www.site.com.br/produto/sku/5293') 
data = json.load(response) 

for a in data: 
    for key, value in a.items(): 
     print key, value 

残りますその結果、あなたたちが見ることができるように、まだサブリスト内のいくつかのキーと値のまま

JSONは、再帰的なデータ構造の定義を許可しているので、以下の再帰関数は、すべてのキーを見つけるだろう、すべての辞書の値のペア1つに遭遇した。複数の（ネストまたはパラレル）ディクショナリで同じキーが複数回発生することに注意してください。

def get_all(myjson): 
    """ Recursively find the keys and associated values in all the dictionaries 
     in the json object or list. 
    """ 
    if isinstance(myjson, dict): 
     for jsonkey, jsonvalue in myjson.items(): 
      if not isinstance(jsonvalue, (dict, list)): 
       yield jsonkey, jsonvalue 
      else: 
       for k, v in get_all(jsonvalue): 
        yield k, v 
    elif isinstance(myjson, list):

まあ、

ご質問は明確ではないが、多分、これはあなたが望むものである：

for a in data: 
    for key, value in a.items(): 
     if key in ['BestInstallmentNumber', 'RealWeightKg', 'NotifyMe', 'HasServiceAtCartPage', 'RewardValue']: 
      print key, value
