HTML中使用如下

{% for i in msg %}
    {{ i.test }}---> {{ i.get('age') }}-->{{ i['city'] }} </br>
{% endfor %}

#可以单独获取第1条数据
{{msg.0.test}} ---> {{ msg.0.get('age') }}-->{{ msg.0['city'] }} </br>

{% for k,v in info.items() %}
    <p>{{ k }} ---> {{ v }} ---> {{ v.test }}---->{{ v['age'] }}---->{{ v.get('city') }}</p>
{% endfor %}

{{ inta }}

{{ inta|safe }}
