What are the benefits of using async context managers in Python?

Async context managers allow for asynchronous resource management, improving performance and readability in concurrent code.

Can you give me an example of how to use one?

Sure! Here's a simple example:

import asyncio

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

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

async def main():
    async with AsyncContext() as context:
        print('Inside the context')

asyncio.run(main())

What are some common use cases for async context managers?

Common use cases include managing database connections, file operations, and network requests, where resources need to be cleaned up asynchronously.

Are there any drawbacks to using async context managers?

One drawback is that they can add complexity to your code, especially if you're not familiar with asynchronous programming.
