What are the best practices for using async context managers in Python?

When using async context managers, ensure you properly handle exceptions and always use 'async with' for resource management.

Can you give me an example of an async context manager?

Sure! Here's a simple example:

import aiofiles

async with aiofiles.open('file.txt', 'r') as f:
    contents = await f.read()

What should I avoid when using async context managers?

Avoid blocking calls within async context managers, as they can hinder the performance of your async code.

How do async context managers differ from regular context managers?

Async context managers use 'async with' and are designed to work with asynchronous code, allowing for non-blocking operations.
