How can I handle errors in async context managers?

You can handle errors in async context managers using try-except blocks within the async context. Would you like an example?

Yes, please provide an example.

Sure! Here's a simple example:

import asyncio

class AsyncContextManager:
    async def __aenter__(self):
        return self
    
    async def __aexit__(self, exc_type, exc_value, traceback):
        if exc_type:
            print(f'Error occurred: {exc_value}')
        return True  # Suppress the exception

async def main():
    async with AsyncContextManager() as manager:
        raise ValueError('An error!')

asyncio.run(main())

What does the return value of aexit do?

The return value of __aexit__ determines whether the exception is suppressed. Returning True suppresses it, while returning False allows it to propagate.
