 shao, hi,

 ajax is javascript, python isn't ajax, so there's an implicit
dichotomy in what you're asking for _but_, there is this:

  http://pyjs.org - pyjamas: a python-to-AJAX compiler and web
framework.

 you can therefore write application front-ends in python that get
compiled into AJAX, to run on a web browser.  the standard pyjamas
user-interface API is _very_ similar to pyqt4 and pygtk2.

 documentation online is quite comprehensive, latest addition is:
http://pyjs.org/book/output/Bookreader.html

 that takes care of the front-end, and a description of how to use
AJAX, including ways to use at least four different JSONRPC back-end
server frameworks is described here:
http://pyjs.org/book/output/Bookreader.html#Rest%20of%20the%20World

 the alternative is for you use a javascript-based AJAX library in
standard HTML, from any back-end server framework of your choice,
coding up the front-end using custom-written javascript.

 the reason you need to write it yourself is that, although many of
the python frameworks come with a _bit_ of AJAX included, it's usually
as part of the "admin" interface: none of the back-end server
frameworks are sufficiently sophisticated to include the kind of
custom functionality you require.

 except pyjamas, which is a full-on compiler, turning python code into
AJAX code, but that's for use in the front-end.

 good luck,

 l.
