When True isn't True enough
I found this brilliant tal:condition inside a Plone template today:
<div class="row"
tal:condition="python:test(content_type.startswith('text'), 1, 0)">
<h2 i18n:translate="heading_file_contents">File contents</h2>
<pre tal:content="here/get_data|here/data|nothing">
</pre>
</div>
