frameword vs application server?

[walterbyrd]

Can somebody help me understand the difference? Not just where Python
is concerned, but in general?

As I understand it, an application server is supposed to be a great
help in developing apps, because most of the business logic is already
there. It seems to me that, usually when applications servers are
discussed, people are talking about Java.

I suppose most popular Python frameworks incorporate an application
server, but I get the idea that those app servers are not nearly as
sophisticed as something like JBoss.

I am not sure if a Python app server, that works like a Java app
server would make sense.
