Hi
I suggest to use the following function that
Advertising
def get_grouped_list(self, seq=[], size=3):
#get the list with all items grouped
return [seq[i:i+size] for i in range(0, len(seq), size)]
that takes as parameter a list and goups items in slices with length = size.
>>> def get_grouped_list(seq=[], size=3):
... return [seq[i:i+size] for i in range(0, len(seq), size)]
...
>>> l = [1,2,3,4,5,6,7,8]
>>> get_grouped_list(l)
[[1, 2, 3], [4, 5, 6], [7, 8]]
>>> get_grouped_list(l, 4)
[[1, 2, 3, 4], [5, 6, 7, 8]]
>>>
Then iterating this is something like:
<tr tal:repeat="slice python:<someobject>.get_grouped_list(yourlist)">
<td tal:repeat="item slice">
<span tal:replace="item" />
</td>
</tr>
Hope this will help.

Hello all , I'm trying to display on the same page a table with (3
columns) with content from a list . I'm trying to batch the results so

Can anyone give me a clue how to do that ?
this is my code:
<table tal:define="Rnumber

python:modules['ZTUtils'].Batch(Rnumber,size=3,start=0)">
<th colspan="3">Main Title</th>
<tr><th>Title 1</th><th>Title 2</th><th>Title 3</th></tr>
<tr>
<td tal:repeat="num batch">
<span tal:condition="python:num < 3"
tal:replace="structure num"> content goes here.. </span>
</td>
</tr> <!-- <tr>
<td tal:repeat="num batch">
<span tal:replace="structure num">
Material goes here </span>
</td>
</tr>
--> </table>
