[Zope] Increment In PT?

[tonylabarbara at aol.com]

Can you give me an example of how to use the enumerate method in a repeat? I've googled this with no luck. Here's my tal:repeat clause:
????? <span tal:repeat="bitem_id bitem_ids;" tal:omit-tag="">
As fas as passing this to a python script, I'd rather not. That seems like too much trouble for something that IMHO should be easy, and if it's not, perhaps the gods of PT would like to do something about it.

TIA,

Tony

| In order to interact with the paypal shopping cart system, they want me to

|  
| <input type="hidden" tal:attributes="value item/name; name python:'item_name_'
| + `x`">
| <input type="hidden" tal:attributes="value item/id; name python:'item_number_'
| + `x`">
| 
| where "x" is a number from 1 on up, where "1" represents the first product in
| the shopping cart, "2" represents the second product, etc. So...we have to do

| Can ZPT handle this, or not?

1) Why not use the "enumerate" method in your repeat?
2) Why not pass the items to a python script that builds the structure you
   need and returns it?
