Let's first briefly review how to create a single host thread in Python that can return a value to the host with a simple example. (This example can also be seen in the single_thread_example.py file under 5 in the repository.) We will do this by using the Thread class in the threading module to create a subclass of Thread, as follows:
import threadingclass PointlessExampleThread(threading.Thread):
