The template code to which you are pointing does not actually generate any
HTML at the point of the {{ for row in rows:}} Python code (i.e., between
the table and tr tags). That is simply a Python statement that begins a for
loop, which loops over the subsequent lines (i.e., the lines from <tr> to
</tr>) -- the loop creates a table row for each row in rows (there should be
a {{pass}} statement at the end to indicate the scope of the loop). The
template system is not inserting text in every place where you see {{ }}. It
only inserts something if preceded by an '=', such as
{{=var_from_controller}}, or when response.write is called explicitly. Does
that make sense? Read ch. 5 for more details:
