What is the Python multiprocessing library?

The Python multiprocessing library allows you to create multiple processes, enabling parallel execution of tasks.

How do I use it to speed up my code?

You can use the Process class to create new processes and the Pool class to manage a pool of worker processes.

Can you give me a simple example?

Sure! Here's a basic example:

from multiprocessing import Process

def worker():
    print('Worker function')

if __name__ == '__main__':
    p = Process(target=worker)
    p.start()
    p.join()

What are the advantages of using multiprocessing over threading?

Multiprocessing avoids the Global Interpreter Lock (GIL) in Python, allowing true parallelism, which can lead to better performance for CPU-bound tasks.
