Jinja2 Basics

In this lesson, you’ll discover how Jinja2 transforms static templates into dynamic content by injecting variables, applying filters, and using control structures. Whether you’re generating HTML pages or automating infrastructure with Ansible, Jinja2 provides a flexible syntax to streamline your workflow.

Introduction to Templating

Templating separates fixed content from dynamic data. For instance, imagine sending a personalized invitation to every employee:

• Keep the main body of the letter in a template.
• Substitute variables like employee name and family members.
• Render hundreds of customized invitations in seconds.

::: note Jinja2 can generate any text-based format—HTML, YAML, INI, or even code. It’s not limited to web pages. :::
