How can I use asyncio tasks in Python 3?

You can use the asyncio library to run tasks concurrently in Python 3. Would you like a simple example?

Yes, please provide a basic example.

Here's a simple example:

import asyncio

async def say_hello():
    print('Hello!')

async def main():
    await say_hello()

asyncio.run(main())

This code defines an asynchronous function and runs it using asyncio.run().

What if I want to run multiple tasks at once?

You can use asyncio.gather() to run multiple tasks concurrently. Here's an example:

async def say_hello():
    print('Hello!')

async def say_goodbye():
    print('Goodbye!')

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

asyncio.run(main())

This will print both messages at the same time.
