As Nicolas says, AddHandler allows you to mix file types and works very 
well. However, you may lose the ability to hide the .py extension in 
your URLs. Assuming a published module in the apps directory, with the 
name foo.py that has a function named bar, SetHandler allows this:


while AddHandler generally permits only this:


Many people prefer the hidden extension for aesthetic reasons and to 
obscure the type of web technology used. While you may be able to 
achieve the same result with AddHandler and MultiViews, this introduces 
its own set of potential problems.

While you are getting used to the idiosyncracies of Publisher, you may 
want to use SetHandler and put *all* of your published modules in one 
directory (like the apps directory mentioned above) and your non-Python 
resources elsewhere. This will help you to avoid common mistakes made by 
beginners and steer you towards developing a structure that works best 
with Publisher.
