What is contextlib in asyncio?

Can you explain what contextlib is in the context of asyncio?

Sure! contextlib is a module in Python that provides utilities for working with context managers. In asyncio, it helps manage resources like network connections or file handles.

How does contextlib improve resource management in asyncio?

It allows you to create context managers that can handle setup and teardown of resources automatically, making your code cleaner and less error-prone.

Can you give me an example of using contextlib with asyncio?

Absolutely! You can use contextlib.asynccontextmanager to define an asynchronous context manager. Here's a simple example:

from contextlib import asynccontextmanager

@asynccontextmanager
def my_async_context():
    print('Setup')
    yield
    print('Teardown')

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

# Run main() in an asyncio event loop.
