In a zope page template, I'm looping thru results from a  
portal_catalog query and writing out a table row for each result  
object.  I also want to keep a running total of a few  variables to  
write out at the end - the last row of the table.  Any suggestions on  
how to do this?  I suspect I have to use the request object, but in  
looking at the class Request.py, I see a set(name,value) method but  
not a corresponding get.  Am I missing something?   This must be a  
common use case.   Thanks much.

Hey, David.

Define the variables with a tal:define and then assign them as you go 
along.

<span tal:repeat="x python:range(1,11)"
	tal:define="y int:6">
	<p tal:define="z python:x*y">
		<span tal:replace="x"/> x <span tal:replace="y"/> = <span 
tal:replace="z"/>
	</p>
</span>

So, in the first span we define y and then change it as the loop rolls 
over the range.

HTH.

hi Jules,

Thanks for your reply.   Unless I misunderstand your code below, I  
don't think this is quite what I'm after.  As I understand what  
you've written, with each repetition of x from 1 to 11, you get a new  
computation of z = x*y, where y = 6.  So, we get z = 6,12,18, etc.   
What I'm after is a running total of z ( sum of z).  So, (sum of z) =  
6, 18, 30, etc.  I want to display the (sum of z) - a total - in the  
final row of the table.

THen define z just above the loop so that z exists outside the scope
of the loop.
Then increment or add to z in each loop.
Don't close the table until after the loop is complete.
Make the last row, just after the loop, the row that shows the total for z.
Wish I could code it up for you, but the previous example shows
plenty.  The only difference is scope and where you print z.
