Question

我有一个从simplejson.load（）函数返回的数据字典（？）。它看起来像这样......

{'status': 'OK', 'results': [{'geometry': {'location_type': 'APPROXIMATE', 'bounds': {'northeast': {'lat': 53.86121, 'lng': -2.045072}, 'southwest': {'lat': 53.80570600000001, 'lng': -2.162588}}, 'viewport': {'northeast': {'lat': 53.8697753, 'lng': -2.0725853}, 'southwest': {'lat': 53.81711019999999, 'lng': -2.2006447}}, 'location': {'lat': 53.84345099999999, 'lng': -2.136615}}, 'address_components': [{'long_name': 'Trawden', 'types': ['sublocality', 'political'], 'short_name': 'Trawden'}, {'long_name': 'Colne', 'types': ['locality', 'political'], 'short_name': 'Colne'}, {'long_name': 'Lancashire', 'types': ['administrative_area_level_2', 'political'], 'short_name': 'Lancs'}, {'long_name': 'United Kingdom', 'types': ['country', 'political'], 'short_name': 'GB'}], 'formatted_address': 'Trawden, Colne, Lancashire, UK', 'types': ['sublocality', 'political']}]}

我如何获得例如结果 - ＆gt; geometry-＆gt; location-＆gt; lat？

这个结构是普通的python字典吗？

编辑：请有人也解释一下simplejson.dumps（）函数。我发现这些文档并不具有启发性。

感谢

非OP编辑：这是JSON，非常印刷：

是的，确实如此。如果将它存储在名为d的变量中，那么您将使用...

d['results'][0]['geometry']['location']

等等。请注意[0]，因为带有键'geometry'的字典在列表中。

simplejson.load()将JSON对象映射到Python dict，将JSON列表映射到list。非常简单;不要过分思考它。

simplejson.dumps()只是与simplejson.loads()相反 - 它接受任何标准的Python对象，并将其转储到一个字符串，该字符串是该对象的JSON表示。例如：

>>> q = {}
>>> q['foo'] = 'bar'
>>> q[1] = 'baz'
>>> simplejson.dumps(q)
'{"1": "baz", "foo": "bar"}'

访问simplejson.load（）输出中的元素
