How can I implement multi-processing in Python?

You can use the multiprocessing module in Python. It allows you to create multiple processes that can run concurrently.

Can you give me a simple example?

Sure! Here's a basic example:

import multiprocessing

def worker(num):
    print(f'Worker: {num}')

if __name__ == '__main__':
    processes = []
    for i in range(5):
        p = multiprocessing.Process(target=worker, args=(i,))
        processes.append(p)
        p.start()

    for p in processes:
        p.join()

What does p.join() do?

p.join() waits for the process p to finish its execution before moving on. It's important for synchronization.

Are there any limitations to using multi-processing?

Yes, multi-processing can have overhead due to inter-process communication and may not be efficient for I/O-bound tasks.
