What are some examples of threading and multiprocessing in Python?

In Python, threading allows you to run multiple threads (smaller units of a process) concurrently. For example, you can use the threading module to create a simple thread that prints numbers.

Can you show me a code example for threading?

Sure! Here's a simple example:

import threading

def print_numbers():
    for i in range(5):
        print(i)

thread = threading.Thread(target=print_numbers)
thread.start()
thread.join()

What about multiprocessing? How is it different?

Multiprocessing uses separate memory spaces and is better for CPU-bound tasks. Here's an example:

from multiprocessing import Process

def print_numbers():
    for i in range(5):
        print(i)

process = Process(target=print_numbers)
process.start()
process.join()

When should I use threading over multiprocessing?

Use threading for I/O-bound tasks (like network requests) and multiprocessing for CPU-bound tasks (like heavy computations).
