empy

EmPy is a powerful, robust and mature templating system for inserting Python code in template text. EmPy takes a source document, processes it, and produces output. This is accomplished via expansions, which are signals to the EmPy system where to act and are indicated with markup. Markup is set off by a customizable prefix (by default the at sign, @). EmPy can expand arbitrary Python expressions, statements and control structures in this way, as well as a variety of additional special forms. The remaining textual data is sent to the output, allowing Python to be used in effect as a markup language.
