What are some examples of using asyncio in Python?

Asyncio is a library to write concurrent code using the async/await syntax. Here are a few examples.

Can you show me a simple example of an asyncio function?

Sure! Here's a basic example:

import asyncio

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

asyncio.run(say_hello())

What about running multiple tasks concurrently?

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

async def task1():
    await asyncio.sleep(2)
    return 'Task 1 done'

async def task2():
    await asyncio.sleep(1)
    return 'Task 2 done'

async def main():
    results = await asyncio.gather(task1(), task2())
    print(results)

asyncio.run(main())
