Python多线程编程：深入理解threading模块及代码实战【第99篇—Multiprocessing模块】_python multithreading模块

import multiprocessing
 
def worker(num):
    """
    A simple worker function that prints numbers.
    :param num: The number to print.
    """
    print(f"Worker: {num}")
 
if __name__ == "__main__":
    # Create a list of numbers to send to multiple processes
    numbers = [1, 2, 3, 4, 5]
 
    # Create a list of processes
    processes = [multiprocessing.Process(target=worker, args=(num,)) for num in numbers]
 
    # Start all the processes
    for process in processes:
        process.start()
 
    # Wait for all processes to finish
    for process in processes:
        process.join()
 
    print("All processes have finished execution.")

这段代码使用Python的multiprocessing模块创建了多个进程，每个进程运行worker函数，并将不同的数字作为参数传入。代码首先定义了worker函数，然后在主程序中，创建了一个进程列表，并启动所有进程。最后，主程序等待所有进程完成工作后再继续执行。这是一个多进程编程的简单示例。
