python - How to render lists of column values into a table using a template (such as Jinja2) -

i trying following (doesn't work, shown convey intended behavior):

<table>   <tr>     <th>column 1</th>     <th>column 2</th>     <th>column 3</th>   </tr>    {% col1_val in col1_values %}     <tr>       <td>{{ col1_val }}</td>       <td>{{ col2_values[col1_values.index(col1_val)] }}</td>       <td>{{ col3_values[col1_values.index(col1_val)] }}</td>     </tr>   {% endfor %} </table> 

where table desired is:

column 1       column 2       column 3 col1_values[0] col2_values[0] col3_values[0] col1_values[1] col2_values[1] col3_values[1] . . . 

where col1_values unique each other.

how should jinja2 template rewritten achieve desired table output? possible without having transpose dimensions of col1_values, col2_values , col3_values? if not, pythonic way of doing transpose?

why not use nested list instead? loop on structure like:

table_values = [[col1_value_0, col2_value_0, col3_value_0], [col1_value_1, col2_value_1, col3_value_1], ...] 

the zip() function can combine 3 colx_values lists if need be:

table_rows = zip(col1_values, col2_values, col3_values) 

now have per-row lists loop over:

{% col1_val, col2_val, col3_val in table_rows %}   <tr>     <td>{{ col1_val }}</td>     <td>{{ col2_val }}</td>     <td>{{ col3_val }}</td>   </tr> {% endfor %}
