How can I use the asyncio library for advanced concurrency in Python?

You can use the asyncio library to manage concurrent tasks using coroutines, event loops, and futures. Would you like a code example?

Yes, please provide a code example that demonstrates this.

Here's a simple example:

import asyncio

async def fetch_data():
    await asyncio.sleep(2)
    return 'Data fetched'

async def main():
    result = await fetch_data()
    print(result)

asyncio.run(main())

This code fetches data asynchronously after a 2-second delay.

What are some common pitfalls when using asyncio?

Common pitfalls include blocking the event loop with synchronous code, not using await properly, and misunderstanding the concurrency model.
