comment – Django template tags

A Django template is a text document or a Python string marked-up using the Django template language. Django being a powerful Batteries included framework provides convenience to rendering data in a template. Django templates not only allow passing data from view to the template but also provide some limited features of programming such as variables, for loops, comments, etc. 
This article revolves about how to use comment tag in Template. Template ignores everything between {% comment %} and {% endcomment %}. An optional note may be inserted in the first tag. For example, this is useful when commenting out code for documenting why the code was disabled. 

Syntax 

{% comment 'comment_name' %}
{% endcomment %}

Example 

{% comment "Optional note" %}
    Commented out text with {{ create_date|date:"c" }}
{% endcomment %}

from django.shortcuts import render

# create a function
def geeks_view(request):
    # create a dictionary
    context = {
        "data" : "<h1>GeeksForGeeks is the Best</h1>",
    }
    # return response
    return render(request, "geeks.html", context)

Create a url path to map to this view. In geeks/urls.py,

Python3

from django.urls import path

# importing views from views..py
from .views import geeks_view

urlpatterns = [
    path('', geeks_view),
]

Create a template in templates/geeks.html, 

HTML

Data uncommented :
{{ data }}
Data commented :
{% comment "Optional note" %}
    {{ data }}
{% endcomment %}

Let’s check is comments are displayed in the template.
