I don't know enough of neither to give you a good answer. But there were two solutions to my question in Python group that helped me understand the issue: http://groups.google.com/group/comp.lang.python/msg/edf12c874e7b2733?hl=en http://groups.google.com/group/comp.lang.python/msg/edf12c87... http://groups.google.com/group/comp.lang.python/msg/439996871519514e?hl=en http://groups.google.com/group/comp.lang.python/msg/43999687... I would like to ask you , if you get a chance, to explain how the following situation is handled in procedural and functional languages: If you want to control how an object is represented when you put it in a template you should define a __str__ method: class Rep(db.model): # Properties ... # Representation def __str__(self): return "\n".join(self.replist) and You can apply a list method to a list object by actually getting the list object. You can't call a list method on a query object or a Rep object. Rep() = Rep object Rep.all() = Query object list(Rep.all()) = List of Rep objects. list(Rep.all())[0] = A single Rep object list(Rep.all())[0].replist = A list So once you have that last step, you have a list. Which you can manipulate like any other Python list. Thanks.
