How do I handle errors in Python asyncio?

In Python asyncio, you can handle errors using try-except blocks within your coroutines. This allows you to catch exceptions that may occur during asynchronous operations.

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 error: {e}')

asyncio.run(main())

What if I want to handle multiple types of exceptions?

You can catch multiple exceptions by specifying them in a tuple in the except clause. For example:

try:
    await risky_task()
except (ValueError, TypeError) as e:
    print(f'Caught an error: {e}')

Is there a way to handle errors globally in asyncio?

Yes, you can set a custom exception handler using loop.set_exception_handler(). This allows you to define how to handle uncaught exceptions globally.
