No expert on this, but ASP's run in the Server and hence a subset of the 
local environment, whilst HTA's run in the browser space. Not running in 
the sandbox means they can invoke applications, but none the less a 
browser cannot automatically launch a python script unless it knows how 
to launch it.

IMHO, an advantage of an HTA is that it is a generic form that isolates 
itself from specifics of the local environment and hence simplifies 
deployment. Instead of your application targetting a specific machine 
environment it is targeting a generic environment which is encapsulated 
in the browser and hence it is possible to create a specific environment 
which is isolated from local machine characteristics. OTOH, ASP's are 
targetting the http server environment which is usually an extension of 
the local machine.
