Slice a list with for loop range function in Django templates

I am developing a Django application about statistics calculations. But now I have faced a problem that I can't solve. I have two lists in my views.py list1 = [5, 6, 7, 8] list2 = [5, 6, 7, 8]. I sent this to Django templates and I also sent 'n' : range(7) as context.

In my html code, there have a code

<table>
    <thead>
        <tr>
            <th>list1</th>
            <th>list2</th>
        </tr>
        <tr>
            <td></td>
            <td></td>
         </tr>
    </thead>
</table>

Now I want to print first value of each list in first row, then second value of each list in second row and so on.

So I have made a code something like this

<table>
    <thead>
        <tr>
            <th>list1</th>
            <th>list2</th>
        </tr>
        {% for i in n %}
        <tr>
            <td> {{ list1.i }} </td>
            <td>{{ list2.i }}</td>
        </tr>
        {% endfor %}
    </thead>
</table>

After writting this code, I am not getting any error but the values are not showing. Instead a blank row and columns are being made.

Please help me to print the values that I want to print.

As a general rule, you should keep all the logic on views. What I'd do is zip the lists and use tuples instead.

views.py:

new_list = zip(list1, list2)
context = {
            'new_list': mylist,
        }

and on templates:

{% for list1_item, list2_item in new_list %}
    <tr>
            <td> {{ list1_item }} </td>
            <td> {{ list2_item }}</td>
    </tr>
{% endfor %}
