Unused 'is' at end of if expression : <pre><code>{% if loop.index is even %}
        &lt;tr class="row1"&gt;
            &lt;td&gt;&lt;a href="/webpage_tracking/report_page?url={{report.url}}&amp;validation={{report.validation}}" target="_blank"&gt;{{report.url}}&lt;/a&gt;&lt;/td&gt;
            &lt;td&gt;{{username}}&lt;/td&gt;
            &lt;td&gt;{{report.validation}}&lt;/td&gt;
            &lt;td&gt;{{report.date}}&lt;/td&gt;
        &lt;/tr&gt;
    {% else %}
        &lt;tr class="row2"&gt;
            &lt;th class="field-object_id"&gt;&lt;a href="/ceeb-admin/ceeb_program/program/{{report.url}}/change/"&gt;{{report.url}}&lt;/a&gt;&lt;/th&gt;
            &lt;td&gt;{{username}}&lt;/td&gt;
            &lt;td&gt;{{report.validation}}&lt;/td&gt;
            &lt;td&gt;{{report.date}}&lt;/td&gt;
        &lt;/tr&gt;
    {% endif %}

<p>The above is my code and I did what tutorial said but it raised the error at first line and I don't know why.</p>
