(Caveat: The below is based on CPython. If you're using IronPython, Jython, or some other implementation, some details may be a little different.) Multiple threads can share state easily by simply referencing each other's variables, but the cost of that is that they'll never actually execute simultaneously. If you want your scripts to run in parallel on multiple CPUs/cores, you need multiple processes. But if you're doing something I/O bound (like servicing sockets), threads work just fine. As to using separate scripts versus the multiprocessing module, that's purely a matter of what looks cleanest. Do whatever suits your code.
