What are the differences between async and sync in Python 3.10?

What are the differences between async and sync in Python 3.10?

In Python 3.10, async functions allow for non-blocking operations, while sync functions block execution until complete.

Can you give me an example of async code?

Sure! Here's a simple async example:

import asyncio

async def main():
    print('Hello')
    await asyncio.sleep(1)
    print('World')

asyncio.run(main())

How does this improve performance?

Async code can handle multiple tasks concurrently, making it more efficient for I/O-bound operations compared to sync code.

Are there any downsides to using async?

Yes, async can add complexity to your code and may not be necessary for CPU-bound tasks where sync might be simpler.
