How do I implement process pools in Python?

You can use the multiprocessing module in Python. It provides a Pool class to manage multiple processes.

Can you show me a simple example of using a process pool?

Sure! Here's a basic example:

from multiprocessing import Pool

def square(x):
    return x * x

if __name__ == '__main__':
    with Pool(4) as p:
        results = p.map(square, [1, 2, 3, 4])
    print(results)

What are the benefits of using process pools?

Process pools help manage multiple processes efficiently, allowing for parallel execution and better resource utilization.

Are there any limitations I should be aware of?

Yes, process pools can have overhead due to inter-process communication and may not be ideal for tasks that require frequent data sharing.
