How does async/await work in Python?

Can you explain how async and await work in Python?

Sure! In Python, async and await are used to define asynchronous functions, allowing you to write non-blocking code.

What is the difference between synchronous and asynchronous programming?

Synchronous programming executes tasks one after another, while asynchronous programming allows tasks to run concurrently, improving efficiency.

Can you give me a simple example of using async and await?

Absolutely! Here's a basic example:

import asyncio

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

asyncio.run(main())

This code prints 'Hello', waits for 1 second, and then prints 'World'.

Are there any limitations to using async/await?

Yes, async/await can only be used with functions defined as async, and it doesn't make CPU-bound tasks faster, only I/O-bound tasks.
