如何遍历从Python / Tornado处理程序传递到Tornado模板的字典？

我试过像

    <div id="statistics-table">

            {% for key, value in statistics %}

            {{key}} : {{value['number']}}

            {% end %}

        </div>

但它不起作用，其中统计数据是字典

statistics = { 1 : {'number' : 2},  2 : {'number' : 8}}

Answer 1

>>> from tornado import template>>> t = template.Template('''... <div id="statistics-table">...&nbsp; &nbsp; &nbsp;{% for key, value in statistics.items() %}...&nbsp; &nbsp; &nbsp;{{key}} : {{value['number']}}...&nbsp; &nbsp; &nbsp;{% end %}... </div>... ''')>>> statistics = { 1 : {'number' : 2},&nbsp; 2 : {'number' : 8}}>>> print(t.generate(statistics=statistics))<div id="statistics-table">&nbsp; &nbsp; 1 : 2&nbsp; &nbsp; 2 : 8</div>选择：<div id="statistics-table">&nbsp; &nbsp; {% for key in statistics %}&nbsp; &nbsp; {{key}} : {{statistics[key]['number']}}&nbsp; &nbsp; {% end %}</div>
