The two basic approaches are event-based asynchronous i/o (there are
various packages for that) and threads.  There are holy wars over which
is better.  Event-driven i/o in Python 2.x was generally done with
callback-based packages like Twisted Matrix (www.twistedmatrix.com).  In
Python 3 there are some nicer mechanisms (coroutines) so the new asyncio
package may be easier to use than Twisted.  I haven't tried it yet.
