Multiptle lines of output

Hi. I am trying to figure out how to display multiple lines of several
values. I know this is basic and done all the time in CGIs, but I am
having trouble wrapping the template around it.

I am reading data from a text file in python one line at a time. For all
lines in the file I want to display each line as a set (list) of values
on a form in a page. Displaying one line is easy in template, but how
would I store multiple lines in HDF and read in a template??

Thanks.
