请给出python实现多进程的示例代码

Python 中可以使用 `multiprocessing` 模块实现多进程。以下是一个简单的示例代码：

import multiprocessing

def worker(number):
    print("Worker %d is running" % number)

if __name__ == '__main__':
    for i in range(5):
        process = multiprocessing.Process(target=worker, args=(i,))
        process.start()

运行结果：

Worker 0 is running
Worker 2 is running
Worker 1 is running
Worker 4 is running
Worker 3 is running
