Template tags in Django are a powerful feature that allows developers to embed Python logic directly into HTML templates, making it possible to dynamically generate content and control the presentation of web pages. These tags are enclosed within {% … %} delimiters and serve as control structures, filters, or variables that Django’s template engine processes during rendering. With template tags, developers can loop through data, conditionally display content, include other templates, or perform various other tasks, all while keeping the separation of logic and presentation intact. This molecularity and flexibility make Django’s template tags a fundamental tool for building dynamic and maintainable web applications, enabling developers to create rich, data-driven web pages with ease.
