What approaches and practices help avoid task blocking in asynchronous processing?

To avoid blocking task execution in asynchronous processing in Python, it is useful to apply the following approaches:

• Use non-blocking input/output operations (e.g., via asyncio, aiohttp).
• Break tasks into smaller parts to prevent blocking the event loop for a long time.
• Apply timeouts and task cancellation (asyncio.wait_for, asyncio.CancelledError).
• Use queues (asyncio.Queue) to manage task streams.
• Avoid synchronous calls within asynchronous code that can block the event loop.

Example of using asyncio with non-blocking wait:

import asyncio

async def task():
    await asyncio.sleep(1)  # non-blocking delay
    print("Task completed")

async def main():
    await asyncio.gather(task(), task())

asyncio.run(main())
