Another great one is zzzeek's mako templating, by far my favorite templating language: http://docs.makotemplates.org/

Anytime I write a web frontend in anything other than Python, I miss it very dearly. But really it's well-suited for any kind of templating work, even code generating—I've seen a few projects use it to generate C code. It's very powerful and doesn't try to dumb itself down because of some dogma about not using logic in templates.
