Jinja2 is a template engine for Python that allows you to create templates for generating dynamic HTML, XML, or other markup. It is similar to Django templates and Mako templates. You can use Jinja2 to insert variables, control structures (e.g. loops and conditionals), and other logic into your templates. To use Jinja2, you first need to install it and then import it into your Python script. Once you have imported Jinja2, you can create a template, render it with data, and output the result.
Here is an example of how to use Jinja2 to render a template:
This will output “Hello, John!”
You can also use template inheritance, loop and conditional statements, macros and other features in Jinja2.
