At least for the "mptest.py" example, did you find and read:

   http://www.dscpl.com.au/articles/modpython-001.html

If you did know of this one and thought it wasn't adequate, please
contribute any feedback so it can be made better.

That configuration will not work properly with mptest.py example code as
the internal way that a Python code file is setup and how your handlers
are defined is somewhat different between mod_python.publisher and a
basic content handler. In mod_python.publisher, it also interprets the
URL in a special way to map requests against the contents of your code
file.

If you did manage to work out the correct URL such that mptest.py did
generate something under mod_python.publisher, you would have found it
probably added the string "0" onto the end of the output wrongly, or the
details of a 500 error generated by Apache may have been appended to the
output in the worst case.

The URL that may have worked for mptest.py under mod_python.publisher
is:

   /~user/python/mptest.py/handler

You should do some more reading into the differences between a basic
content handler and a mod_python.publisher published object and how URL
mapping works in mod_python.publisher.

If all you are after is a way of having different basic content handlers
in distinct files and having the URLs map to each appropriately, you
might also consider looking at Vampire, as it provides this sort of
functionality for mod_python.
