我正在使用Tumblr API —— 我想构建一个小小的 doo-dad，它将我所有的帖子拉到我的各种 Tumblr 上，并每周一次将它们归档到我的 WordPress 博客中。
因此，每次脚本运行时，我都想记录最大帖子 ID。所以我试图让这样的事情起作用：
jdata = json.loads(rawjson)
jposts = jdata['response']['posts']
for post in jposts:
print post['id']
print max(jposts['id'])
我得到的是很多帖子 ID（预期）， list indices must be integers, not str但如果我这样做，print type(post['id'])Python 会将它们识别为<type 'long'>. 所以......我在这里做错了什么？
这是Tumblr 的示例输出片段，您可以将其用于rawjson

"body":"\u003Cp\u003EIn the last months this blog has experienced a progressive decline in the number of produced posts. There are several reasons that come to my mind to explain why is that, but probably the better one is about the fact that I lost motivation. Unexpectedly, despite the lack of regular updates the blog gained more and more followers. [That’s flattering, but at the same time makes me suspicious about the relationship between quality of a blog and number of followers.]\u00a0\u003C\/p\u003E\n\u003Cp\u003EAnyway, I always feel a little lost when I follow a blog and it slowly fades away, and then it just stops posting, without saying anything, so I thought to make this post.\u003C\/p\u003E\n\u003Cp\u003EI’m not going to update \u003Cem\u003Escipsy\u003C\/em\u003E anymore.
