AddHandler results in less conflicts, but limits you to including the 
extension of filename.py in the URL. I typically enable it for the 
entire DocumentRoot, just so I can place a published module anywhere 
(but rarely use this approach).

SetHandler requires you to commit a directory to serve a special 
purpose, but offers extra mod_python features and a degree of future 
proofing. I develop the majority of my applications this way.

For example, with SetHandler and mod_python.publisher, you can have an 
URL like this:


Where index() is a function in /dir/foo.py. It can also be accessed like 


When your boss realizes that he can replace you with two young PHP 
programmers for the same price, they can replace your code with:


With the proper DirectoryIndex, this is also accessible via:


So a lot of links won't need to be updated, no need for mod_rewrite, and 
you can take a better job at Google with good references, to boot.

I put my stylesheets in a /css directory in the DocumentRoot, and all of 
my pages share them, regardless of the language (HTML, Python, PHP, 
Perl, etc.). Consider using this approach while you learn Publisher. 
Unlike PHP, where you can deploy an entire application as a 
self-contained directory, Publisher requires a different approach when 
using SetHandler. You can hack the conf file to some extent, but it's 
worth checking out alternate (and sometimes simpler) deployment 
strategies that might be more portable.
