Hi I suggest to use the following function that 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. Dragos Nicolas Georgakopoulos wrote:
