我正在努力创建一个简单的Python脚本，最终会告诉您在给定月份中发布了多少博客条目，并且pyblog应用程序非常有用。
但是，当我创建博客对象时，我不知道如何访问它的各种属性。我可以通过从字典中打印一个项目来打印出来，如下面的摘录中所示：
print blog.get_recent_posts(1)

但是我怎样才能让它提供DateTime信息呢？
答案 0 :(得分：2)
如果blog.get_recent_posts(1)是一本字典，print会显示前导和尾随括号，而你所展示的内容则从不知名的地方开始，到另一个中间地带结束 - 绝对荒谬。
我将假设您制作了一些奇怪的副本和过去的错误，而是字典。在这种情况下，例如创建日期很容易，只需索引：
print blog.get_recent_posts(1)['dateCreated']
编辑：OP编辑了Q以显示整个结果（并提到了一些有用的错误信息），这些信息一起表明函数的结果是一个包含一个字典的列表。鉴于这种情况，正确的陈述变为：
print blog.get_recent_posts(1)[0]['dateCreated']
