I might mention that ZSQL results can be stored using tal:define, as
well. Here, it is not so much about avoiding python: calls, as it is
about avoiding expensive calls, and/or extraneous methods. Although, I
often find it increases readability, as well.
<body tal:define="sqlres container/my_sql_method">
<tr tal:repeat="rows sqlres">
<p><span tal:replace="python:len(sqlres)"> rows were found.</p>
