Jinja2

It provides a Django inspired non-XML syntax but supports an optional sandboxed environment and inline expressions.

Features:

• Configurable syntax. If generating LaTeX or other formats with Jinja2 the user can change the delimiters to something that integrates better into the LaTeX markup.
• Fast. While performance is not the primarily target of Jinja2 it's surprisingly fast. The overhead compared to regular Python code was reduced to the very minimum.
• Easy to debug. Jinja2 integrates directly into the Python traceback system which allows to debug Jinja2 templates with regular Python debugging helpers.
• Secure. It's possible to evaluate untrusted template code if the optional sandbox is enabled. This allows Jinja2 to be used as templating language for applications where users may modify the template design.
