python - Using index from iterated list

Question

I'm trying to display values from a different list based on the index that is currently being iterated over on another list but cannot figure out how to access the individual items..

{% for row in myarray.all %}
    <tr>
    <th>{{ my_other_array_where_I_cant_access_elements.forloop.counter }}</th>
    <td>{{ row }}</td>
    </tr>
{% endfor %}

As you can see I have tried to use forloop.counter but this doesn't display anything, it just creates an empty table header element.

My other array is defined within the view as the following, and if I remove the forloop.counter then I am able to see the entire array printed to the table header

 my_other_array_where_I_cant_access_elements = ["X", "Y", "Z", "XX", "YY"]

Please let me know if I've missed any required details.

It sounds like you want to iterate over two lists at the same time, in other words zip() lists.

If this is the case, it is better to do this in the view and pass inside the context:

headers = ["X", "Y", "Z", "XX", "YY"]
data = zip(headers, myarray.all())
return render(request, 'template.html', {'data': data})

Then, in the template:

{% for header, row in data %}
    <tr>
        <th>{{ header }}</th>
        <td>{{ row }}</td>
    </tr>
{% endfor %}
