The basic idea of using the Python module threading to write multithreaded routines is to threading. The thread class derives a subclass from it, implements the business logic in the run function of the subclass, creates a thread pool of the subclass object, and executes the execution function of the subclass object. Here is an example of multithreaded programming using the threading
