How do I use context managers in async Python?

In async Python, you can use context managers with the async with statement. This allows you to manage resources like files or network connections efficiently.

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

Sure! Here's a simple example:

import aiofiles

async def read_file(file_path):
    async with aiofiles.open(file_path, 'r') as f:
        contents = await f.read()
    return contents

What libraries support async context managers?

Libraries like aiofiles, asyncio, and httpx support async context managers. They help manage resources in an asynchronous way.

Are there any best practices for using async context managers?

Yes, always ensure that your context managers are properly awaited and handle exceptions gracefully to avoid resource leaks.
