What are context managers in asynchronous code?

What are context managers in asynchronous code?

Context managers in asynchronous code are used to manage resources, ensuring they are properly acquired and released.

Can you give me an example of how to use a context manager in async functions?

Sure! You can use the async with statement to create a context manager. For example:

async with some_async_resource() as resource:
    await resource.do_something()

What happens if an exception occurs within the context manager?

If an exception occurs, the context manager's __exit__ method is called, allowing for cleanup actions to be performed.

Are there built-in context managers for async code in Python?

Yes, Python's asyncio library provides built-in context managers like asyncio.Lock and asyncio.Semaphore.
