所以，我正在使用pytumblr API从Tumblr检索博客文章。我想检索帖子并仅提取帖子内容。 技术上 Tumblr通过dict将它发送给我，但格式非常非常混乱。除此之外，它还使用单引号和双引号！这是我的代码：
post = client.posts(blogName, type = 'text', tag = 'suggestion', limit = 1)
postformat = str(post[u'posts']).replace("[", "").replace("]", "")
blog = dict(ast.literal_eval(postformat))
print(post[u'body']).replace("<p>", "").replace("</p>", "")
首先，Tumblr给了我一个只有3个键的非常大的字典，但每个字典都有一个字典！ （???）。所以，我需要拿出我正在寻找的第一个键，然后使用ast将该键的内容转换回dict。当我尝试这个时，我得到了一个不同的错误。因此，我删除了post周围的括号，并使用了ast来尝试解释内容。但是当我这样做的时候，就会在第3行抛出一个SyntaxError。这里的post[u'posts']是原始的，非常令人困惑的格式。但是由于stackoverflow将它放在一行上，我还把它放在了http://pastebin.com/9fnuS2F6

答案 0 :(得分：1)
语法错误是由删除括号引起的。在字典里面的某处有一个标签列表，你输入的字符串是：
fetchedTimestamps = c("30-1-2016 10:00:00", "30-1-2016 10:15:00", "30-1-2016 10:45:00")
fetchedTimestamps = strptime(fetchedTimestamps, format = "%d-%m-%Y %X")
# [1] "2016-01-30 10:00:00 CET" "2016-01-30 10:15:00 CET" "2016-01-30 10:45:00 CET"
expectedTimestamps = seq(min(fetchedTimestamps), max(fetchedTimestamps), by = "15 mins")
# [1] "2016-01-30 10:00:00 CET" "2016-01-30 10:15:00 CET" "2016-01-30 10:30:00 CET" "2016-01-30 10:45:00 CET"
expectedTimestamps %in% fetchedTimestamps
# [1] FALSE FALSE FALSE FALSE
as.numeric(expectedTimestamps) %in% as.numeric(fetchedTimestamps)
# [1] TRUE TRUE FALSE TRUE
也就是说，它从字典表示法切换到列表表示法，因为标签周围的... u'title': None, u'tags': u'queued', u'suggestion', u'suggestion blog', ...
消失了。
我怀疑[]只是一个帖子列表，post['posts']是第一个，post['posts'][0]是您正在寻找的主体。
