What is the purpose of async and await in Python?

Async and await are used in Python to write concurrent code using the async/await syntax, making it easier to manage asynchronous operations.

Can you give me an example of how to use async and await?

Sure! Here's a simple example:

import asyncio

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

asyncio.run(main())

What happens if I don't use await with an async function?

If you don't use await, the async function will return a coroutine object instead of executing the function, which means the code won't run as expected.

Are there any performance benefits to using async and await?

Yes, using async and await can improve performance by allowing your program to handle other tasks while waiting for I/O operations to complete, making it more efficient.
