What are the best practices for using asyncio in Python?

Some best practices include using async/await syntax, avoiding blocking calls, and using asyncio.gather for concurrency.

Can you explain why blocking calls are a problem?

Blocking calls can halt the event loop, preventing other tasks from running, which defeats the purpose of asynchronous programming.

What is asyncio.gather and how do I use it?

asyncio.gather allows you to run multiple coroutines concurrently and wait for them to finish. You can use it like this: await asyncio.gather(coro1(), coro2()).

Are there any libraries that work well with asyncio?

Yes, libraries like aiohttp for HTTP requests and databases like asyncpg for PostgreSQL are great for async programming.
