How say Andreas and Tres, I made a script

[suma_py]
parameters:
  rec, campo
code:
  suma=0
  for r in rec:
     suma+=r[campo]
  return suma


[index_html]
<div tal:define="items aquery()">
   <div tal:repeat="item items">
      ...
  </div>
   <div>
       el importe es <span tal:content="suma_py(items, 'importe')">
       la cantidad es <span tal:content="suma_py(items, 'cantidad')">
   </div>
</div>
