Question

我有一个如下所示的JSON文件：

{
"meta": {
    "limit": 25,
    "cache-expiry": 3600
},
"objects": [
    {
        "name": "Elements Automotive",
        "locality": "Dallas",
        "street_address": "8700 Sovereign Row",
        "cuisines": [],
        "postal_code": "75247",
        "categories": [
            "other"
        ],
        "has_menu": false,
        "country": "United States",
        "lat": 32.8191949123164,
        "id": "000e090545789efeca0c",
        "website_url": "http://elementsautomotive.com/",
        "resource_uri": "/v1_0/venue/000e090545789efeca0c/"
    }
]
}

如何从对象中获取密钥列表（＆＃34;名称＆＃34;，＆＃34; locality＆＃34;等）？

编辑：对不起，密钥都是统一的 - 我只是把它们中的一些剪掉了以保持代码/帖子的简短。

Answer 1

 data["objects"][0].keys()
 ['cuisines', 'postal_code', 'lat', 'id', 'categories', 'name', 'locality', 'country', 'street_address', 'has_menu', 'website_url', 'resource_uri']

Answer 2

with open('jsondatafile') as fp:
    data = json.load(fp)
    print list(data['objects'][0])

应该做的伎俩...
