我正在从 python 脚本访问 Google Books API，并且需要在获得的 JSON 对象中获取特定值。例如，如果您遵循以下步骤:
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 键中包含的书籍描述。我在使用 urllib2 获取后使用 json.load 加载它。
我已尝试执行以下操作但无济于事:
a = json.load(urllib2.urlopen('https://www.googleapis.com/books/v1/volumes?q=9781607055389'))
print a.items[0].description
最佳答案
description 在另一本字典中，您忘记了:
>>> 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 get() 函数，或者执行我所做的操作。 .items 起作用的原因是内置函数 .items()，它返回字典的结构。
