Python 检查Jinja2中变量的类型

我想检查Jinja2中变量的类型。如果它是变量类型是dictionary，那么我必须在段落中打印一些文本，如果它不是dict，那么我必须打印一些其他值

我在这里尝试的是

{% if {{result}} is dict %}
<tr>
<td>
<p> The details are not here </p>
</td>
</tr>
{% else %}
{% for each_value in result %}
<tr>
<td>each_value.student_name</td>
</tr>
{% endfor %}
{% endif %}

结果的另一种格式是

II.result=[{'student_name':'b','student_id':2,'student_email':'my_nameb@gmail.com','time':[{'st':1,'et':2},{'st':3,'et':4}]}]

---

您应该将

{%if{result}}是dict%}

替换为

{%if result是mapping%}

II.result=[{'student_name':'b','student_id':2,'student_email':'my_nameb@gmail.com','time':[{'st':1,'et':2},{'st':3,'et':4}]}]

Expected result
If I get the format 'I' then the if loop should get execute.
If I get the format 'II' then the else loop should get execute.

Actual result
jinja2.exceptions.TemplateSyntaxError: expected token ':', got '}'
