That's one way, if you want to use the python parser for your
"templates".  You could create a template parser (and with it your own
template language) for expanding various constructs (eg loops and
variables) embedded in HTML.  That's all a template is, anyways --
some data with special markers, the markers are replaced by a
processor and the result is spit out.  This is what the Zope Page
Template (TAL) authors did.

Yeah, go do that!  :-)

Sure some do.  PHP people do the same thing.  And Perl people.  And C
people.  You can even use ASM or raw machine code to write CGI
"scripts".  I recommended using tools that provide as high-level a
view of the system as possible.
