What are some examples of concurrency in Python?

Concurrency in Python can be achieved using threading, multiprocessing, and async features. Would you like examples of each?

Yes, please provide examples for threading and async.

For threading, you can use the threading module to run tasks in parallel. For example:

import threading

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

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

For async, you can use the asyncio library:

import asyncio

async def print_numbers():
    for i in range(5):
        print(i)
        await asyncio.sleep(1)

asyncio.run(print_numbers())

These examples show how to run tasks concurrently.

What about multiprocessing? Can you give an example?

Sure! The multiprocessing module allows you to create separate processes. Here's a simple example:

from multiprocessing import Process

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

if __name__ == '__main__':
    process = Process(target=print_numbers)
    process.start()
    process.join()

This will run the print_numbers function in a separate process.
