How can I use context managers in asynchronous code?

You can use context managers in asynchronous code by utilizing the async with statement. This allows you to manage resources efficiently.

Can you give me an example of using async with?

Sure! Here's a simple example:

import aiofiles

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

What happens if I don't use a context manager?

If you don't use a context manager, you might forget to release resources, leading to memory leaks or file locks.

Are there any libraries that support async context managers?

Yes, libraries like aiofiles for file operations and asyncio for managing asynchronous tasks support async context managers.
