Template engines in Python are tools used to generate dynamic HTML (or other text formats) by combining static templates with dynamic data. They're commonly used in web development to separate presentation (HTML) from application logic (Python code), enhancing code readability and maintainability.

A template is a text file (often HTML) with placeholders for dynamic content. The template engine processes this file, replaces placeholders with actual data provided by the application, and outputs the final rendered result.

How They Work:

  1. Template Creation: You write a template file with placeholders (e.g., {{ name }} or {% if user %}).

  2. Data Injection: You pass a context (a dictionary of data) to the template engine.

  3. Rendering: The engine processes the template, replaces placeholders with the corresponding data, and outputs the final content.

Common Python Template Engines:

  • Jinja2: Popular and powerful, used by Flask. Supports control structures (loops, conditions), filters, and custom tags.

  • Django Templates: Built into Django, similar to Jinja2 but with added security and template inheritance features.

  • Mako and Chameleon: Other options that emphasize performance or XML support.

Template engines streamline web development by cleanly separating logic from layout, making code more modular and reusable.
