CherryPy itself doesn't come bundled with a specific template engine; instead, it's quite flexible and allows integration with various template engines of your choice. CherryPy's templating is agnostic, enabling you to use different engines based on your preferences or project requirements.

Some of the popular template engines that work well with CherryPy include :

Jinja2 : Jinja2 is a widely used template engine in the Python ecosystem. It provides a powerful and feature-rich environment for creating templates. CherryPy can easily integrate with Jinja2 using the jinja2 package.

Mako : Mako is another templating engine known for its speed and simplicity. CherryPy can work seamlessly with Mako templates.

Genshi : Genshi is a template engine that emphasizes XML-based templating. CherryPy supports Genshi templates as well.

Cheetah : CherryPy also has compatibility with Cheetah, which is a template engine that uses Python code within templates. To use these template engines with CherryPy, you typically need to install the respective Python packages for the desired engine and then set up your CherryPy application to use the chosen template engine. Here's a basic example of how you might integrate Jinja2 with CherryPy :

import cherrypy
from jinja2 import Environment, FileSystemLoader

class HelloWorld:
    @cherrypy.expose
    def index(self):
        env = Environment(loader=FileSystemLoader('templates'))
        template = env.get_template('index.html')
        return template.render(message="Hello, CherryPy and Jinja2!")

if __name__ == '__main__':
    cherrypy.quickstart(HelloWorld())​

This example assumes that you have a 'templates' folder containing 'index.html' within your project directory. It uses Jinja2 to render the 'index.html' template with a simple message.

Remember, the setup might differ slightly depending on the template engine you choose, but CherryPy's flexibility allows you to seamlessly integrate various template engines into your web applications.
