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 template, but also provides some limited features of a programming such as variables, for loops, etc.
This article revolves about how to use a variable in Template. A variable outputs a value from the context, which is a dict-like object mapping keys to values.
Syntax:
{{ variable_name }}
Example:
Variables are surrounded by {{ and }} like this:
My first name is {{ first_name }}. My last name is {{ last_name }}.
With a context of {‘first_name’: ‘Naveen’, ‘last_name’: ‘Arora’}, this template renders to:
My first name is Naveen. My last name is Arora.
