What are some examples of asynchronous programming in Python?

Asynchronous programming in Python allows you to write code that can handle multiple tasks at once. For example, using the asyncio library, you can create coroutines that run concurrently. Would you like to see a specific example?

Yes, please show me a simple example using asyncio.

Sure! Here's a simple example:

import asyncio

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

async def main():
    await say_hello()

asyncio.run(main())

This code defines an asynchronous function that prints 'Hello', waits for 1 second, and then prints 'World!'. Would you like to know more about how it works?

Yes, how does the await keyword function in this example?

The await keyword is used to pause the execution of the coroutine until the awaited task is complete. In this case, it pauses the say_hello function for 1 second while allowing other tasks to run in the meantime. This is what makes it asynchronous!
