Here’s a brief overview of how to use Jinja2 in Python:

1. Install Jinja2: You can install Jinja2 using pip, the package manager for Python:

2. Import Jinja2: In your Python code, you need to import Jinja2’s Environment and FileSystemLoader:

3. Create a template environment: Jinja2 requires an environment to load and render templates. You need to create an instance of Environment, providing the template folder path:

4. Load a template: To use a template, you need to load it from the environment using its filename (without the extension):

5. Render the template with data: To render the template with dynamic data, you pass a dictionary of variables to the render method:

In this example, the variables name and age will be accessible in the template, and you can use them like this:

The {{ ... }} syntax denotes template expressions that will be replaced with the corresponding values from the data dictionary.

6. Save or display the output: Once you’ve rendered the template with the data, you can save it to a file or display it as needed:

Jinja2 also supports control structures like if, for, and filters to manipulate data within the templates.

That’s a basic overview of using Jinja2 in Python. It’s a powerful tool that enables you to create dynamic content and maintain clean separation between code and presentation. You can use it in web frameworks like Flask and Django or in any Python project that requires dynamic template rendering.
