How can I use context managers in asyncio?

You can use context managers in asyncio to manage resources like connections or files efficiently. They help ensure that resources are properly acquired and released.

Can you give me an example of using a context manager with an async function?

Sure! Here's a simple example:

import asyncio

class AsyncContextManager:
    async def __aenter__(self):
        print('Entering context')
        return self

    async def __aexit__(self, exc_type, exc_val, exc_tb):
        print('Exiting context')

async def main():
    async with AsyncContextManager():
        print('Inside context')

asyncio.run(main())

What happens if an exception occurs inside the context manager?

If an exception occurs, the __aexit__ method will still be called, allowing you to handle the exception gracefully. You can check the exc_type, exc_val, and exc_tb parameters to manage the error.
