How can I use asyncio for synchronization in Python?

You can use asyncio's synchronization primitives like Lock, Event, and Semaphore to manage concurrent tasks.

Can you give me an example of using a Lock?

Sure! Here's a simple example:

import asyncio

lock = asyncio.Lock()

async def critical_section():
    async with lock:
        # critical section code here
        print('Lock acquired!')
        await asyncio.sleep(1)
        print('Lock released!')

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

asyncio.run(main())

What happens if multiple tasks try to access the critical section?

If multiple tasks try to access the critical section, only one will acquire the lock at a time, while others will wait.

Are there other synchronization primitives I should know about?

Yes, you should also look into Event for signaling between tasks and Semaphore for limiting concurrent access.
