The usual mechanism is the pyserial module. Google is your friend.

I believe you need to implement the observer pattern. There have
already been several successful implementations of this, and
again Google should be capable of finding them. For example:

Most Python implementations support threading, and there are a
number of other asynchronous service techniques. There should
be absolutely no problem.
