Ques 26. What is Jinja templating?

Django comes with the support for many popular templating engines, and by default, it comes with one very powerful templating engine, called Jinja Templating. The latest version is Jinja 2.

Ques 27. What is user authentication in Django?

Django has a built-in user authentication system capable of handling different objects, such as users, groups, user-permissions, and some cookie-based user sessions.
