字典中嵌套数据的问题

Question

f = open("sample_flickr_response.json","r")
search_result_diction = json.loads(f.read())
print search_result_diction
f.close()
search_result_diction["id"]
for sample_photo_ids in sample_photo_ids["id"]:
    print sample_photo_ids['raw']

我有一些问题与我的上述代码。我试图打开文件并将文件中的数据加载到一个名为search\u result的变量中_用词变量搜索结果字典包含一个非常复杂的字典（见下文）。每个项目都有一个id。我正在尝试创建一个列表，列出搜索结果词汇数据表示的每个项目的所有id，并将该列表保存在名为sample photo id的变量中。你知道吗

我收到的当前错误是KeyError:'id'。你知道吗

下面是示例flickr的字典_响应.json你知道吗

Answer 1

借用@roganjosh's comment，一种获得id的惯用方法：

ids = [item["id"] for item in search_result_diction["photos"]["photo"]]

将给您一个list的id，然后您可以打印：

for id in ids:
    print id

输出：

33119881551
32433652893
33091881772
...

在一个for循环中，更接近您在问题中使用的内容，这也会给您相同的结果：

for item in search_result_diction["photos"]["photo"]:
    print item["id"]
