如果当前迭代与前一个迭代不同，则为循环模板

Question

我想拥有

{% for user_id, x, y in information %}
    {% if it is the first time that user_id is different from the previous iteration %}
        do something
    {% elseif user_id is different from the user_id in the previous iteration %}
        do something
    {% endif %}

谁能帮忙。谢谢！！！
