I'm in the process of building a web application using cherrypy.
What template technology do you recommend I use?
If you mean a templating engine, I've had some success using mako with cherrypy. They just seem to play nicely together.
Mako is extremely easy to get started with and customize, which is, I assume, also two of your major reasons for choosing cherrypy. The cherrypy official tutorial also uses mako, and you can see a simple sample application there.
