Only in a very general sense, if you mean the separation of concerns
between loggers and handlers. There isn't a general-purpose pub/sub
infrastructure built into it.

Of course, pub/sub is just one type of message architecture. I would
say that it would be nice to have a Python messaging package which had
pub/sub as one of several different approaches - which is often done
these days using things like RabbitMQ. Are there any such (pure-Python
or Python + C) packages out there which are generally accepted as
being head and shoulders above others in the same category?

It may be too early to bless any one messaging package for the stdlib
- "let a thounsand flowers bloom" and all that. In any case, stdlib
inclusion can be a double-edged sword in terms of backward-
compatibility constraints, leading to reduced developer/maintainer
flexibility going forward.
