[Zope] Page Template --> tal:repeat

["Echeverria Rabi, Cristián"]

Thanks for your help.
Thanks to yours suggestions I solved my current problem.

I've something like this:

1. A main page template that get the values and call a Python Script
2. A Python Script that query a database (calling another script). Then I
have the result of the query in a variable. Then my script call another page
template to do the rendering of the result.
3. A page template to render the results of the query (so I need to pass the
variable with the result of the query).

All yours suggestion worked, but I needed to include a line in my script
before calling the final page template:

contest.REQUEST.set('value',query_result)

... and then everything worked.

I'm not sure this is the right way to do it, I'm just starting with zope,
Any other comments?

Thanks
Cristian

Minor typo there: that's

<tr tal:define="value request/value" tal:repeat="row python:range(value)">

                            ^

or you can do it all at once, as

<tr tal:repeat="row python: range(request.value)">

or, to *make sure* that the value comes from the form variables passed by
your last script (as opposed to coming from some other place in the request
variable):

<tr tal:repeat="row python: range(request.form['value'])">
