我正在从 python 脚本访问 Google Books API，我需要在我得到的 JSON 对象中获取特定值。例如，如果你遵循这个：
https://www.googleapis.com/books/v1/volumes?q=9781607055389
您将看到我尝试使用的 JSON 对象。我需要获取description密钥中包含的书籍描述。我在json.load使用urllib2.
我尝试执行以下操作无济于事：
a = json.load(urllib2.urlopen('https://www.googleapis.com/books/v1/volumes?q=9781607055389'))
print a.items[0].description
description在另一本字典中，你忘记了：
>>> print a['items'][0]['volumeInfo']['description']

您访问字典值的意图不是您在 python 中所做的。您可以使用该get()功能，也可以执行我所做的。起作用的原因.items是由于内置函数.items()，它返回字典的结构。
尝试使用以下内容：
a['items'][0]['volumeInfo']['description']
注意， a.items() 和 a['items'] 不是一回事。a.items() 为您提供元组列表中的键值对。
