tornado 模板中如何使用 datetime 模块

[bwangel]

<time class="entry-date">{{% datetime.date.today().year %}}</time>

我在一个 tornado 模板中使用的 datetime 模块，如上所示！

但是运行的时候出错，错误代码如下所示：

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/tornado-4.3.dev1-py2.7-linux-x86_64.egg/tornado/web.py", line 1411, in _execute

    _tt_tmp = % datetime.date.today().year %  # index.html:16 (via base.html:56)
              ^
SyntaxError: invalid syntax

我在这个网址中看到了 datetime 的使用示例，照着实例来会出问题，请问正确的方法应该如何写！

好吧，我错了，模板语法写错了！

`<time class="entry-date">{{ datetime.date.today().year }}</time>`
