Python has an API that allow us to write applications with multiple threads. To get started with multithreading, we are going to create a new thread inside a python class and call it ThreadWorker.py. This class extends from threading.Thread and contains the code to manage one thread:

import threading
class ThreadWorker(threading.Thread):
    # Our workers constructor
    def __init__(self):
        super(ThreadWorker, self).__init__()
    def run(self):
        for i in range(10):
           print(i)

Now that we have our thread worker class, we can start to work on our main class. Create a new python file, call it main.py, and put the following code in:

import threading
from ThreadWorker import ThreadWorker

def main():
    # This initializes ''thread'' as an instance of our Worker Thread
   thread = ThreadWorker()
    # This is the code needed to run our thread
    thread.start()

if __name__ == "__main__":  
    main()
