How do I handle exceptions in Python asyncio?

In Python asyncio, you can handle exceptions using try-except blocks within your async functions.

Can you give me an example of that?

Sure! Here's a simple example:

import asyncio

async def risky_task():
    raise ValueError('An error occurred!')

async def main():
    try:
        await risky_task()
    except ValueError as e:
        print(f'Caught an exception: {e}')

asyncio.run(main())

What happens if I don't handle the exception?

If you don't handle the exception, it will propagate up and cause your program to crash, terminating the event loop.

Are there any best practices for exception handling in asyncio?

Yes, it's best to handle exceptions as close to the source as possible and to log them for debugging purposes.
