Unless you get mod_wsgi from trunk you won't have a change getting it
to work with python 3 and even then I'm not sure the trunk is fully
3.n compatible yet.
I use the Django framework for almost all my web projects now. Django
is written in python, but uses Python v2 not V3. There are few if any
packages that use Python 3 yet, Guido expected at least five years for
people to make the switch and we're only 1.5 years into his plan.
Stick with Python 2.6 for now. With this said you should have no
problem using JS/AJAX to update your site's pages, mod_wsgi won't
stand in your way with this at all.
This is a short and not very robust example of a mod_wsgi hook file:
def application(environ, start_response):
status = '200 OK'
output = "Hello World! (Oh Shit it works.)"
response_headers = [('Content-Type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
return [output]
This can be made into a class using the __call__ method.
