还是以 , 分隔吧, 模版里

<td valign="middle">
    {% for ip in mod[2].split(',') %}
      <p>{{ ip }}</p>
    {% endfor %}
</td>

测试代码

>>> from jinja2 import Template
>>> tmpl = """{% for ip in ips.split(',') %} <p>{{ ip }}</p> {% endfor %}"""
>>> t = Template(tmpl)
>>> print t.render({"ips": "127.0.0.1,192.168.1.1"})
