How can I implement concurrency in Python?

You can use the asyncio library for asynchronous programming or the concurrent.futures module for threading and multiprocessing.

What are the differences between threading and multiprocessing?

Threading is suitable for I/O-bound tasks, while multiprocessing is better for CPU-bound tasks due to the Global Interpreter Lock (GIL).

Can you give me an example of using asyncio?

Sure! Here's a simple example:

import asyncio

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

asyncio.run(say_hello())

What about using threads for web scraping?

Using threads can speed up web scraping by allowing multiple requests to be processed simultaneously. You can use the requests library with ThreadPoolExecutor from concurrent.futures.
