I suggest to use the thread or threading module. The threading
provides a higher level interface (it's build on the top
of the thread module). The way how to implement a solution for
your needs depends on your needs. E.g. you can create a worker
threads that runs in a loop. To periodic execution you could
use time.sleep() to delay execution for a period of time.
