What is the purpose of 'async' and 'yield' in Python?

Can you explain the purpose of 'async' and 'yield' in Python?

Sure! 'async' is used to define asynchronous functions, allowing for non-blocking code execution. 'yield' is used in generators to produce a value and pause the function's execution, resuming later.

How do 'async' and 'yield' work together in a program?

They can work together in asynchronous generators. You can use 'async def' to define an async generator function and 'yield' to produce values asynchronously.

Can you give me a simple code example?

Certainly! Here's a simple example:

import asyncio

async def async_gen():
    for i in range(3):
        await asyncio.sleep(1)  # Simulate an async operation
        yield i

async def main():
    async for value in async_gen():
        print(value)

asyncio.run(main())
