What is async/await in Python 3?

Can you explain what async/await is in Python 3?

Sure! Async/await is a syntax in Python 3 that allows you to write asynchronous code more easily. It helps manage tasks that can run concurrently without blocking the main thread.

How does it differ from traditional threading?

Unlike traditional threading, async/await uses a single-threaded event loop to manage tasks. This means it can handle many tasks at once without the overhead of multiple threads.

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

Of course! Here's a simple example:

import asyncio

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

asyncio.run(say_hello())

What are some common use cases for async/await?

Common use cases include web scraping, handling I/O-bound tasks, and building web servers that need to manage many connections simultaneously.
