What is Python multiprocessing and how does it work?

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

Can you explain the difference between threading and multiprocessing?

Threading uses shared memory and is suitable for I/O-bound tasks, while multiprocessing uses separate memory spaces, ideal for CPU-bound tasks.

How do I implement multiprocessing in a simple Python program?

You can use the multiprocessing module to create a Process object and start it. Here's a basic example: from multiprocessing import Process; def task(): print('Hello from process!'); p = Process(target=task); p.start(); p.join().

What are some common use cases for multiprocessing?

Common use cases include data processing, web scraping, and any CPU-intensive tasks that can benefit from parallel execution.
