Answer 1

根据您的JSON格式，您可以这样做：

your_json['data'].keys()

Answer 2

希望这有帮助。

result = []
json = {u'data': {u'244332': {u'hotel_data_node': {u'_id': 919824916605752258L, u'ids': {u'bkg': [u'244332'], u'voy': 9174725345440343760L}, u'vendor_info': {u'vendor_id': u'244332', u'vendor': u'bkg'}}},

for key in json['data']: 
    result += json['data'][key]['hotel_data_node']['ids']['bkg']
print(result)
>>>[u'244332', u'1066459', u'1354690', u'1300150', u'472468', u'300420', u'722942']

Answer 3

我想这是重复问题，请参阅：

Accessing JSON elements

也是为了'你'：

Python: json.loads returns items prefixing with 'u'
