Question

我有模板.html存储在变量“email_html”中我还有一个名为“info”的字典，定义为

info = {'username': u'snip', 'netlink': [u'> F: IL00091 = AMS/VIE/LE-134621 : None : None | O: at-vie01a- : xe-3/1/3 _ et-2/1/21 : nl-ams05a- | W: None : None _ None : None *'], 'end': [2015, 8, 15, 11], 'notes': u'', 'usms': u'ccc', 'start': [2015, 8, 15, 11], 'netelement': [u'> at-vie01a- * x.x.x.x']}

但是当我尝试将info变量加载到模板时：

template = jinja2.Template(open(email_html).read())
html = template.render(**info)

我收到以下错误：

In [13]: html = template.render(**info)

    379         except (TypeError, LookupError):
    380             if isinstance(argument, string_types):

UndefinedError: 'info' is undefined

这是普通的Python（没有Django，没有Flask）。你能告诉我做错了吗？
