Stuck while iterating the dictionary in the django template

I have this dictionary:-

a = {'title': ['Turning a MacBook into a Touchscreen with $1 of Hardware (2018)', 'Supercentenarians are concentrated into regions with no birth certificates', 'Open list of GDPR fines so far'], 'url': ['https://www.anishathalye.com/2018/04/03/macbook-touchscreen/', 'https://www.biorxiv.org/content/10.1101/704080v1', 'https://github.com/lknik/gdpr/blob/master/fines/README.md'], 'type': ['story', 'story', 'story'], 'n': [0, 1, 2]}

I passed it into the template. Now, what I want is to get the first 'title' along with the 'type', with its 'url'. I tried the following code:-

<ul>
{% for i in n %}
<br/>
{{i}}
<li>{{title.i}}</li><br/>
<li>{{url.i}}</li>
{%endfor%}

But couldn't get the desired output. My desired output is:-
Title: Turning a MacBook into a Touchscreen with $1 of Hardware (2018)
URL: https://www.anishathalye.com/2018/04/03/macbook-touchscreen/
TYPE: story

In this way a continuous list of Titles followed by url and type.
The output I get is a blank screen.
Please help me out.

I wouldn't recommend your context like that though,
but if you don't want change it, u can use custom simple filters.

from django import template

register = template.Library()

@register.filter
def index(my_list, idx):
    return my_list[idx]

then in your template (don't forget to load it first)

{% for item in title %}
Title: {{ item }}
URL:  {{ url|index:forloop.counter0 }}
Type: {{ type|index:forloop.counter0 }}
{% endfor %}


I recommend this way, it more be simple if you use zip in your views

title = ['Turning a MacBook into a Touchscreen with $1 of Hardware (2018)', 'Supercentenarians are concentrated into regions with no birth certificates', 'Open list of GDPR fines so far']

url = ['https://www.anishathalye.com/2018/04/03/macbook-touchscreen/', 'https://www.biorxiv.org/content/10.1101/704080v1', 'https://github.com/lknik/gdpr/blob/master/fines/README.md']

type = ['story', 'story', 'story']

zipped = zip(title, url, type)
a = {'zipped': zipped}

then in your template

{% for title, url, type in zipped %}
Title: {{ title }}
URL: {{ url }}
Type: {{ type }}
{% endfor %}


or another way, use list of dictionaries instead

my list = [
    {'title': 'Turning a MacBook into a Touchscreen with $1 of Hardware (2018)', 'url': 'https://www.anishathalye.com/2018/04/03/macbook-touchscreen/', 'type':'story'},
    {'title': '...', 'url': '...', 'type': 'story'}, 
    {'title': '...', 'url': '...', 'type': 'story'}
]
a = {'my_list': my_list}

then iterate it with:

{% for item in my_list %}
Title: {{ item.title}}
URL: {{ item.url}}
Type: {{ item.type }}
{% endfor %}

How about something like this: 

<ul>
  {% for key, values in a.items %}
    {% if key != 'n' %}
      <br/>
      <li>{{ key }}: {{ values.0}}</li>
      {% endif %}
    {% endfor %}
</ul>
