Whats wrong with repeat here? repeat would give you if <yourmethod>
and variabe defining the same time. You can do it without repeat,
but it will be worser.

<span tal:repeat="foo here/your_ZSql_method" 
tal:content="foo/column">wopp</span>

ZSQL method always return an object which behaves like a list
of zero or more objects which behave like an dictionary and
an object with attributes the same time (so you can write
result[index].column or result[index]['column']

You should really really not hesiate to learn python any more :)
Just give the tutorial on python.org a try, it will clarify
much of your questions out.

Keep in mind: python does not bite. :)

I would like to see that too. But unfortunately...

Guess why ;) Try to build up an example ;)

Um. The replacement consists of Python Scripts + ZPT, not ZPT allone.
