Several ways to start a thread in python

This article mainly introduces four ways to start threads in Python.

1. Using the threading module

Create a Thread object and then call the start() method to start the thread.

import threading

def func():
    print("Hello, World!")

t = threading.Thread(target=func)
t.start()

2. Inherit threading.Thread class

Override the run() method and call the start() method to start the thread.

import threading

class MyThread(threading.Thread):
    def run(self):
        print("Hello, World!")

t = MyThread()
t.start()

3. Using the concurrent.futures module

Use the submit() method of the ThreadPoolExecutor class to submit a task, automatically create a thread pool and execute the task.

import concurrent.futures

def func():
    print("Hello, World!")

with concurrent.futures.ThreadPoolExecutor() as executor:
    future = executor.submit(func)

4. Use the Process class of the multiprocessing module

Create a process, and start a thread within the process.

import multiprocessing
import threading

def func():
    print("Hello, World!")

if __name__ == "__main__":
    p = multiprocessing.Process(target=func)
    p.start()
    p.join()

The above is an introduction to several ways to start threads in python. I hope it will be helpful to you.
