What is Python multiprocessing and how can I use it?

Python multiprocessing is a module that allows you to create multiple processes, enabling parallel execution of tasks.

Can you give me an example of how to use it?

Sure! Here's a simple 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 are the advantages of using multiprocessing over threading?

Multiprocessing can take advantage of multiple CPU cores, while threading is limited by Python's Global Interpreter Lock (GIL), making multiprocessing more efficient for CPU-bound tasks.
