Would zip work?

I’ve already tried
for k,w,m in zip(kpi, weightage, marks_obtained)
but its giving error “Zip not found” something like this.

I tried this work arround and it’s working fine for me.
May be it’ll work for you also.

list_1  = [1, 2,3,4]
list_2 = [1,2,3,4]
<table>
{% for i in list_1 %}
      {% set item_1 = list_1[loop.index-1] %}
      {% set item_2 = list_2[loop.index-1] %}
     <tr>
           <td> {{ item_1 }} </td>
           <td>  {{ item_2 }} </td>
    </tr>
{% endfor %}
  </table>

loop.index always start with index 1

NOTE:
Your all lists len must be balance or you can handle the condition for exception index out of range

There is a problem with this solution. if list 2 length is not equal to list 1 then it’ll error out.
You can do it like this
list_length = what ever is the smaller length out of list_1 and list2

loop through the list_length and then use it to index the lists.

{%- set statements = ['profile', 'target', 'product'] %}
{%- set conditions  = ['easy', 'eat', 'apple'] %}
{%- for i in range(statements|length) %}
    Item {{i}} - {{statements[i]}}: {{conditions[i]}}
{%- endfor %}
