What is the method for creating multiple processes in Python?

There are two common methods used in Python to create multiple processes.

1. parallel processing
2. running multiple processes simultaneously
3. Procedure
4. using multiple processors

from multiprocessing import Process

def func():
    # 进程需要执行的代码
    print("Hello, world!")

if __name__ == '__main__':
    # 创建进程对象
    p = Process(target=func)

    # 启动进程
    p.start()

    # 等待进程结束
    p.join()

1. concurrent futures.
2. Concurrent futures technology.
3. parallel processing in Python

from concurrent.futures import ProcessPoolExecutor

def func():
    # 进程需要执行的代码
    print("Hello, world!")

if __name__ == '__main__':
    # 创建进程池对象
    with ProcessPoolExecutor() as executor:
        # 提交任务给进程池
        future = executor.submit(func)

        # 等待任务完成
        result = future.result()

Using the above two methods, it is possible to create multiple processes in Python and utilize multi-core processors to concurrently execute tasks, thus improving the program’s efficiency.
