How can I implement concurrency in Python?

You can implement concurrency in Python using threading, multiprocessing, or async features. Which one are you interested in?

I'm interested in using async. Can you give me an example?

Sure! Here's a simple example using asyncio:

import asyncio

async def say_hello():
    print('Hello')
    await asyncio.sleep(1)
    print('World!')

async def main():
    await asyncio.gather(say_hello(), say_hello())

asyncio.run(main())

This will print 'Hello' twice, then wait for a second before printing 'World!' twice.

What if I want to handle multiple tasks concurrently?

You can use asyncio.gather() to run multiple coroutines concurrently. Just pass them as arguments to gather().
